Struct Attributes

pub struct Attributes(/* private fields */);

a bitset for all possible attributes

Implementations

impl Attributes

pub const fn none() -> Attributes

Returns the empty bitset.

pub const fn with(self, attribute: Attribute) -> Attributes

Returns a copy of the bitset with the given attribute set. If it’s already set, this returns the bitset unmodified.

pub const fn without(self, attribute: Attribute) -> Attributes

Returns a copy of the bitset with the given attribute unset. If it’s not set, this returns the bitset unmodified.

pub fn set(&mut self, attribute: Attribute)

Sets the attribute. If it’s already set, this does nothing.

pub fn unset(&mut self, attribute: Attribute)

Unsets the attribute. If it’s not set, this changes nothing.

pub fn toggle(&mut self, attribute: Attribute)

Sets the attribute if it’s unset, unset it if it is set.

pub const fn has(self, attribute: Attribute) -> bool

Returns whether the attribute is set.

pub fn extend(&mut self, attributes: Attributes)

Sets all the passed attributes. Removes none.

pub const fn is_empty(self) -> bool

Returns whether there is no attribute set.

Performs the ^ operation.

impl BitXor for Attributes

type Output = Attributes

The resulting type after applying the ^ operator.

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl From<&[Attribute]> for Attributes

fn from(arr: &[Attribute]) -> Attributes

Converts to this type from the input type.

impl From<Attribute> for Attributes

fn from(attribute: Attribute) -> Attributes

Converts to this type from the input type.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> 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.
