Struct HashedWheelBuilder

pub struct HashedWheelBuilder { /* private fields */ }

Builder for configuring different options for a HashedWheel.

Implementations

impl HashedWheelBuilder

pub fn with_tick_duration(self, duration: Duration) -> HashedWheelBuilder

Sets the tick duration which sets the resolution for the timer.

Any timeouts will be rounded up based on the tick duration.

pub fn with_num_slots(self, num_slots: usize) -> HashedWheelBuilder

Sets the number of slots used for ticks.

Controls how many slots we have for timeouts. The less number of collisions there are (where a collision is when two or more items in the same slot have different timeouts), the more efficient operations we can perform.

pub fn with_init_capacity(self, init_capacity: usize) -> HashedWheelBuilder

Sets the initial capacity for timer storage.

This is the number of timeouts we can initially store.

pub fn with_max_capacity(self, max_capacity: usize) -> HashedWheelBuilder

Sets the maximum capacity for timer storage.

This is the maximum number of timeouts we can ever store.

pub fn with_max_timeout(self, timeout: Duration) -> HashedWheelBuilder

Sets the maximum timeout for any timer.

Defaults to tick_duration * num_slots.

pub fn tick_duration(&self) -> Duration

Get the tick duration that was set.

pub fn num_slots(&self) -> usize

Get the number of slots that were set.

pub fn init_capacity(&self) -> usize

Get the initial capacity for timer storage that was set.

pub fn max_capacity(&self) -> usize

Get the maximum capacity for timer storage that was set.

pub fn max_timeout(&self) -> Duration

Get the maximum timeout that was set.

pub fn build<T>(self) -> HashedWheel<T>

Build a new HashedWheel from the current builder.
