This method will return None if any unknown bits are set.

pub fn insert(&mut self, other: Command)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Command)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Command, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Command) -> Command

The intersection of a source flags value with the complement of a target flags value (&!).

pub const fn symmetric_difference(self, other: Command) -> Command

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Command

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl Command

pub const fn iter(&self) -> Iter<Command>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<Command>

Yield a set of contained named flags values.

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.
