Struct WheelBuilder 

pub struct WheelBuilder { /* private fields */ }

Builder for configuring a timer wheel.

Defaults match the Linux kernel timer wheel (1ms tick, 64 slots/level, 8x multiplier, 7 levels → ~4.7 hour range).

Examples

use std::time::{Duration, Instant};
use nexus_timer::{Wheel, WheelBuilder};

let now = Instant::now();

// All defaults
let wheel: Wheel<u64> = WheelBuilder::default().unbounded(4096).build(now);

// Custom config
let wheel: Wheel<u64> = WheelBuilder::default()
    .tick_duration(Duration::from_micros(100))
    .slots_per_level(32)
    .unbounded(4096)
    .build(now);

Implementations

impl WheelBuilder

pub fn new() -> Self

Creates a new builder with default configuration.

pub fn tick_duration(self, d: Duration) -> Self

Sets the tick duration. Default: 1ms.

pub fn slots_per_level(self, n: usize) -> Self

Sets the number of slots per level. Must be a power of 2. Default: 64.

pub fn clk_shift(self, s: u32) -> Self

Sets the bit shift between levels (multiplier = 2^clk_shift). Default: 3 (8x).

pub fn num_levels(self, n: usize) -> Self

Sets the number of levels. Default: 7.

pub fn unbounded(self, chunk_capacity: usize) -> UnboundedWheelBuilder

Transitions to an unbounded wheel builder.

chunk_capacity is the slab chunk size (entries per chunk). The slab grows by adding new chunks as needed.

pub fn bounded(self, capacity: usize) -> BoundedWheelBuilder

Transitions to a bounded wheel builder.

capacity is the maximum number of concurrent timers.
