Implementations

impl SupportsFeature

pub fn is_declaration(&self) -> bool

Returns true if self is of variant Declaration.

pub fn as_declaration(&self) -> Option<&Box<Declaration>>

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

pub fn as_mut_declaration(&mut self) -> Option<&mut Box<Declaration>>

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

pub fn expect_declaration(self) -> Box<Declaration>where
    Self: Debug,

Unwraps the value, yielding the content of Declaration.

Panics

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

pub fn declaration(self) -> Option<Box<Declaration>>

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

pub fn is_function(&self) -> bool

Returns true if self is of variant Function.

pub fn as_function(&self) -> Option<&Function>

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

pub fn as_mut_function(&mut self) -> Option<&mut Function>

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

pub fn expect_function(self) -> Functionwhere
    Self: Debug,

Unwraps the value, yielding the content of Function.

Panics

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

pub fn function(self) -> Option<Function>

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

Trait Implementations

impl Clone for SupportsFeature

fn clone(&self) -> SupportsFeature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SupportsFeature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SupportsFeature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EqIgnoreSpan for SupportsFeature

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

impl From<Box<Declaration, Global>> for SupportsFeature

fn from(v: Box<Declaration>) -> Self

Converts to this type from the input type.

impl From<Function> for SupportsFeature

fn from(v: Function) -> Self

Converts to this type from the input type.

impl From<SupportsFeature> for SupportsInParens

fn from(v: SupportsFeature) -> Self

Converts to this type from the input type.

impl Hash for SupportsFeature

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<SupportsFeature> for SupportsFeature

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

This method tests for self and other values to be equal, and is used by ==.

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

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for SupportsFeature

fn span(&self) -> Span
