impl Capabilities
源代码pub const fn from_bits_truncate(bits: c_uint) -> Self
pub const fn from_bits_truncate(bits: c_uint) -> Self
从位值转换,未知的位会被清除。
源代码pub const fn from_bits_retain(bits: c_uint) -> Self
pub const fn from_bits_retain(bits: c_uint) -> Self
按位值原样转换(保留所有位)。
源代码pub fn from_name(name: &str) -> Option<Self>
pub fn from_name(name: &str) -> Option<Self>
获取一个 flags 值,其位为具有给定名称的 flag 所对应的位。若 name 为空或不与任何已命名的 flag 对应,则该方法将返回 None。
源代码pub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
判断 other 中是否至少有一位也在 self 中被设置。
源代码pub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
判断 other 中所有已设置的位是否都在 self 中被设置(即 self ⊇ other)。
源代码pub fn remove(&mut self, other: Self)
pub fn remove(&mut self, other: Self)
self 与 other 的补的交集(&!)。当 other 含有未知位时,该方法不等价于 self & !other。remove 不会截断 other,而 ! 运算符会。
源代码pub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
当 value 为 true 时调用 insert,当 value 为 false 时调用 remove。
源代码pub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
self 与 other 的按位与(&)。
源代码pub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
self 与 other 的补的交集(&!)。当 other 含有未知位时,该方法不等价于 self & !other。该方法不会截断 other,而 ! 运算符会。
源代码pub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
self 与 other 的按位异或(^)。
源代码pub const fn complement(self) -> Self
pub const fn complement(self) -> Self
对 self 的位按位取反(!),并截断结果。
源代码§impl Capabilities
impl Capabilities
源代码pub const fn iter(&self) -> Iter<Capabilities>
pub const fn iter(&self) -> Iter<Capabilities>
Yield a set of contained flags values.
每个产出的 flag 值对应一个已定义的具名 flag。任何未知位将作为最终的flags 值一起产出。
源代码pub const fn iter_names(&self) -> IterNames<Capabilities>
pub const fn iter_names(&self) -> IterNames<Capabilities>
逐个产出该 flags 值中所包含的已命名 flag 集合。
This method is like iter, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
