Struct WheelConfigBuilder 

pub struct WheelConfigBuilder { /* private fields */ }

时间轮配置构建器 (Timing Wheel Configuration Builder)

Implementations

impl WheelConfigBuilder

pub fn l0_tick_duration(self, duration: Duration) -> Self

设置 L0 层 tick 时长 (Set L0 layer tick duration)

pub fn l0_slot_count(self, count: usize) -> Self

设置 L0 层槽位数量 (Set L0 layer slot count)

pub fn l1_tick_duration(self, duration: Duration) -> Self

设置 L1 层 tick 时长 (Set L1 layer tick duration)

pub fn l1_slot_count(self, count: usize) -> Self

设置 L1 层槽位数量 (Set L1 layer slot count)

pub fn build(self) -> Result<WheelConfig, TimerError>

构建配置并进行验证 (Build and validate configuration)

返回 (Returns)

• Ok(WheelConfig): 配置有效 (Configuration is valid)
• Err(TimerError): 配置验证失败 (Configuration validation failed)

验证规则 (Validation Rules)

• L0 tick 时长必须大于 0 (L0 tick duration must be greater than 0)
• L1 tick 时长必须大于 0 (L1 tick duration must be greater than 0)
• L0 槽位数量必须大于 0 且是 2 的幂次方 (L0 slot count must be greater than 0 and power of 2)
• L1 槽位数量必须大于 0 且是 2 的幂次方 (L1 slot count must be greater than 0 and power of 2)
• L1 tick 必须是 L0 tick 的整数倍 (L1 tick must be an integer multiple of L0 tick)
