Module Polymarket_rate_limiter.BuilderSource

Fluent builder for rate limit configurations.

This module provides a chainable API for building route configurations, similar to the Rust route-ratelimit crate.

Example:

  route () |> host "api.example.com" |> method_ "POST" |> path "/orders"
  |> limit ~requests:100 ~window_seconds:10.0
  |> limit ~requests:1000 ~window_seconds:600.0
  |> on_limit Delay |> build
Sourcetype t

Builder state

Sourceval route : unit -> t

Start building a route configuration

Pattern Matching

Sourceval host : string -> t -> t

Match requests to a specific host

Sourceval method_ : string -> t -> t

Match requests with a specific HTTP method (case-insensitive)

Sourceval path : string -> t -> t

Match requests with a path prefix (uses segment boundaries)

Rate Limits

Multiple limits can be applied to the same route. All limits must pass for a request to proceed. This enables burst + sustained limit patterns.

Sourceval limit : requests:int -> window_seconds:float -> t -> t

Add a rate limit. Can be called multiple times to add multiple limits. Example: limit ~requests:100 ~window_seconds:10.0 for 100 req/10s

Behavior

Sourceval on_limit : Types.behavior -> t -> t

Set what happens when the rate limit is exceeded.

  • Delay: Sleep until the request can proceed (default)
  • Error: Return an error immediately

Building

Build the final route configuration. Uses Delay behavior if not specified. At least one limit must be configured.

Convenience Constructors

Sourceval simple : ?host:string -> ?method_:string -> ?path:string -> requests:int -> window_seconds:float -> ?behavior:Types.behavior -> unit -> Types.route_config

Create a simple route configuration with a single limit. Example:

  simple ~host:"api.example.com" ~requests:100 ~window_seconds:10.0 ()
Sourceval global : requests:int -> window_seconds:float -> behavior:Types.behavior -> Types.route_config

Create a global rate limit that matches all routes

Sourceval per_host : host:string -> requests:int -> window_seconds:float -> behavior:Types.behavior -> Types.route_config

Create a rate limit for all routes to a specific host

Sourceval per_endpoint : host:string -> method_:string -> path:string -> requests:int -> window_seconds:float -> behavior:Types.behavior -> Types.route_config

Create a rate limit for a specific endpoint

Host-Scoped Builder

For organizing rate limits by host, similar to the Rust library's .host("...", |h| ...) pattern.

Sourcetype host_builder

Builder for routes scoped to a host

Sourceval for_host : string -> host_builder

Start building routes for a specific host

Sourceval add_route : t -> host_builder -> host_builder

Add a route to the host builder. The route inherits the host.

Sourceval build_host : host_builder -> Types.route_config list

Build all routes for this host
