std

Riot's standard library for building real applications.

std is the package most Riot users should start with. It is not just a bag of helpers. It is the application-facing layer that brings together Riot's actor runtime, supervision model, filesystem and process I/O, networking, data formats, testing, benchmarking, configuration, logging, and the everyday utility modules you end up reaching for in real programs.

If you are building an application, a service, a CLI, a tool, or a test suite in Riot, this is usually the right package to depend on first.

Install

riot add std

When to reach for `std`

Use std when you want one cohesive surface for:

actor-oriented concurrency and supervision;
files, directories, paths, and generic I/O;
JSON, TOML, CSV, XML, S-expressions, and text encoding;
TCP, TLS, HTTP data types, URIs, and addresses;
structured logging, telemetry, configuration, and environment handling;
testing, benchmarking, worker pools, and background jobs;
Unicode-aware strings, iterators, collections, graphs, and utilities.

Use a lower-level package like kernel only when you specifically need its lower-level primitives or you are implementing infrastructure that sits under std.

Quick start

open Std

let load_config = fun path ->
  Fs.read (Path.v path)
  |> Result.and_then Data.Toml.parse_string

let main = fun ~args:_ ->
  let config =
    load_config "riot.toml"
    |> Result.expect ~msg:"failed to load config"
  in
  ignore config;
  Log.info "loaded config successfully";
  Ok ()

let () = Runtime.run ~main ~args:Env.args ()

What `std` includes

std is broad. The easiest way to approach it is by domain.

Application and process model

Application for ordered startup and shutdown of multi-part systems.
Agent for simple shared state built on actors.
Supervisor for fault-tolerant process trees.
Process, Pid, Message, Task, Timer, and WorkerPool for everyday process lifecycle, async work, time-based work, and parallel execution.
Global and System for runtime-wide state and system queries.

Filesystem, paths, and I/O

Fs for high-level filesystem work.
Fs.File, Fs.Fd, Fs.Metadata, Fs.Permissions, and Fs.ReadDir for more focused file and directory control.
Fs.FileWatcher and Fs.Walker for watching and traversing directory trees.
IO for generic readers, writers, and streaming-style APIs.
Path for typed, composable filesystem paths.
Archive and Compress for tar and gzip operations.

Networking and protocols

Net as the umbrella networking namespace.
Net.Addr, Net.Uri, Net.TcpClient, Net.TcpListener, Net.TcpServer, Net.TcpStream, and Net.TlsStream.
Net.Http and its submodules: Header, Method, Request, Response, Status, and Version.

Data formats and encoding

Data.Json, Data.Toml, Data.Csv, Data.Xml, and Data.Sexp.
Encoding.Base16, Encoding.Base32, Encoding.Base64, Encoding.Base85, and Encoding.Octal.
Regex and Glob for matching and pattern compilation.

Logging, configuration, and observability

Log and its related modules for structured logging.
Telemetry for emitting measurements and events.
Config, Config.Loader, Config.Provider, Config.Server, Config.Spec, and Config.Validator.
Env and Command for environment access and external process execution.

Collections and iteration

Collections and its core structures, including Deque and Heap.
Iter and iterator/cursor tooling for functional and parsing-oriented iteration.
Graph, Graph.SimpleGraph, Graph.Dot, and Graph.Mermaid.

Time, dates, randomness, and identifiers

Time, Time.Duration, Time.Instant, and Time.SystemTime.
Datetime and Calendar.
Random, UUID, and Version.

Text, Unicode, and language-facing utilities

String, Char, Uchar, and Unicode.
Unicode-aware helpers for graphemes, segmentation, width, and UTF-8/UTF-16.
Diff, ArgParser, Sync, Type, Ref, Ptr, and Exception.

Cryptography and hashing

Crypto, Crypto.Digest, and Crypto.Hasher.
Concrete algorithms including Md5, Sha1, Sha256, and Sha512.

Testing and benchmarking

Test and its supporting modules: Assertions, Cli, FixtureRunner, Reporter, Snapshot, TestContext, and more.
Bench and its runner/reporting surface for repeatable benchmarks.

Module map

If you like scanning names before digging deeper, this is the condensed map of the package surface:

Runtime and application: Application, Agent, Supervisor, Process, Pid, Message, Task, Timer, WorkerPool, Global, System
Filesystem and I/O: Fs, Fs.File, Fs.Fd, Fs.Metadata, Fs.Permissions, Fs.ReadDir, Fs.FileWatcher, Fs.Walker, IO, Path, Archive, Compress
Networking: Net, Net.Addr, Net.Uri, Net.TcpClient, Net.TcpListener, Net.TcpServer, Net.TcpStream, Net.TlsStream, Net.Http
Data and codecs: Data.Json, Data.Toml, Data.Csv, Data.Xml, Data.Sexp, Encoding, Regex, Glob
Ops and runtime support: Config, Log, Telemetry, Env, Command
Core utilities: Result, Option, String, Bool, Char, Int, Int32, Int64, Float, UUID, Version, Random, Ref, Ptr, Type
Iteration and structure: Collections, Iter, Graph, Diff, Sync
Time: Time, Datetime, Calendar
Unicode: Unicode, Uchar
Crypto: Crypto
Validation and tooling: Test, Bench, ArgParser, GenStage

Examples

std already ships with runnable examples. Two good entry points are:

riot run -p std hello_world
riot run -p std walker_find -- --count-only packages/std/examples

The examples directory currently includes:

hello_world.ml for the smallest possible Std + Runtime.run program.
walker_find.ml for recursive filesystem walking and glob-based filtering.
test_uri.ml for URI parsing and manipulation.
unicode_example.ml, test_unicode_tables.ml, and word_navigation_example.ml for Unicode and text segmentation work.
uuid_test.ml for UUID generation and formatting.
bench_demo.ml, vector_bench.ml, and hashmap_bench.ml for the benchmark surface.
debug_query.ml and line_wrapping_example.ml for focused text and tooling helpers.

Where to read next

src/std.mli is the authoritative top-level module guide.
examples/ is the fastest way to see package pieces working together.
tests/ is useful when you want executable examples of specific edge cases and expected behavior.

Related packages

kernel is the lower-level substrate beneath std.
actors is a compatibility facade over Std.Runtime while the repo finishes migrating off the old package boundary.
blink builds an HTTP client on top of the same model.
suri is the web framework layer when you need HTTP routing and server-side application structure.
