Expand description

一个位平面的真值向量。

Tuple Fields§

§0: u64

Implementations§

Source§

impl BitPlane

Source

pub const ZERO: Self

全 0 平面。

Source

pub const ONES: Self

全 1 平面。

Source

pub const fn with_bit(bit: u32) -> Self

构造指定位为 1 的平面。

环绕语义:位号按 bit % 64 取模,with_bit(64) 等价于 with_bit(0)。 需要拒绝越界位号时用 checked_with_bit。

Source

pub const fn checked_with_bit(bit: u32) -> Option<Self>

构造指定位为 1 的平面;bit >= 64 返回 None。

Source

pub const fn bit(self, bit: u32) -> bool

该平面第 bit 位是否为 1。

环绕语义:位号按 bit % 64 取模,bit(64) 读的是第 0 位。

Source

pub const fn checked_bit(self, bit: u32) -> Option<bool>

读取第 bit 位;bit >= 64 返回 None。

Source

pub const fn count_ones(self) -> u32

平面内 1 的个数(popcount)。
