Struct BooleanFlag 

pub struct BooleanFlag { /* private fields */ }

A flag paired with a boolean state.

Implementations

impl BooleanFlag

pub const fn new(flag: Flag, enabled: bool) -> Self

Creates a boolean flag primitive.

pub const fn enabled(flag: Flag) -> Self

Creates an enabled boolean flag.

pub const fn disabled(flag: Flag) -> Self

Creates a disabled boolean flag.

pub const fn flag(&self) -> &Flag

Returns the underlying flag.

pub const fn is_enabled(&self) -> bool

Returns whether the flag is enabled.

Trait Implementations

impl Clone for BooleanFlag

fn clone(&self) -> BooleanFlag

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BooleanFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for BooleanFlag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BooleanFlag

fn eq(&self, other: &BooleanFlag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
