Implementations

impl MediaFeatureName

pub const fn is_ident(&self) -> bool

Returns true if self is of variant Ident.

pub fn as_ident(&self) -> Option<&Ident>

Returns Some if self is a reference of variant Ident, and None otherwise.

pub fn as_mut_ident(&mut self) -> Option<&mut Ident>

Returns Some if self is a mutable reference of variant Ident, and None otherwise.

pub fn expect_ident(self) -> Ident

where Self: Debug,

Unwraps the value, yielding the content of Ident.

Panics

Panics if the value is not Ident, with a panic message including the content of self.

pub fn ident(self) -> Option<Ident>

Returns Some if self is of variant Ident, and None otherwise.

pub const fn is_extension_name(&self) -> bool

Returns true if self is of variant ExtensionName.

pub fn as_extension_name(&self) -> Option<&ExtensionName>

Returns Some if self is a reference of variant ExtensionName, and None otherwise.

pub fn as_mut_extension_name(&mut self) -> Option<&mut ExtensionName>

Returns Some if self is a mutable reference of variant ExtensionName, and None otherwise.

pub fn expect_extension_name(self) -> ExtensionName

where Self: Debug,

Unwraps the value, yielding the content of ExtensionName.

Panics

Panics if the value is not ExtensionName, with a panic message including the content of self.

pub fn extension_name(self) -> Option<ExtensionName>

Returns Some if self is of variant ExtensionName, and None otherwise.

Trait Implementations

impl Clone for MediaFeatureName

fn clone(&self) -> MediaFeatureName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MediaFeatureName

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

Formats the value using the given formatter.

impl EqIgnoreSpan for MediaFeatureName

fn eq_ignore_span(&self, other: &Self) -> bool

impl From<ExtensionName> for MediaFeatureName

fn from(v: ExtensionName) -> Self

Converts to this type from the input type.

impl From<Ident> for MediaFeatureName

fn from(v: Ident) -> Self

Converts to this type from the input type.

impl Hash for MediaFeatureName

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,

impl PartialEq for MediaFeatureName

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