Source

pub struct RateLimiter { /* private fields */ }

Expand description

Rate limiter managing per-tool and global windows.

Implementations§

Source §

impl RateLimiter

Source

pub fn new(global_rpm: u64, default_tool_rpm: u64, burst_allowance: u64) -> Self

Create a new rate limiter.

global_rpm: Maximum total requests per minute across all tools.
default_tool_rpm: Default per-tool RPM limit.
burst_allowance: Extra burst capacity per tool.

Source

pub fn from_config(config: &RateLimiterConfig) -> Self

Create a rate limiter from a RateLimiterConfig.

Per-tool overrides from the config are applied immediately.

Source

pub fn set_override(&self, tool: &str, rpm: u64)

Set a per-tool RPM override.

Source

pub fn try_acquire(&self, tool: &str) -> Result<(), u64>

Try to acquire a permit for a tool invocation.

Returns Ok(()) if allowed, Err(retry_after_ms) if rate-limited.

Source

pub fn stats(&self) -> HashMap<String, f64>

Get statistics for all tracked tools.

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send> ⓘ

Converts Arc<Trait> (where Trait: DowncastSync) to Arc<Any>, which can then be downcast into Arc<ConcreteType> where ConcreteType implements Trait.
