Implementations§

Source§

impl<'a> TypeParamRef<'a>

Source

pub const fn is_type_var(&self) -> bool

Returns true if self is of variant TypeVar.

Source

pub fn as_type_var(&self) -> Option<&&'a TypeParamTypeVar>

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

Source

pub fn as_mut_type_var(&mut self) -> Option<&mut &'a TypeParamTypeVar>

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

Source

pub fn expect_type_var(self) -> &'a TypeParamTypeVar
where Self: Debug,

Unwraps the value, yielding the content of TypeVar.

§Panics

Panics if the value is not TypeVar. In debug builds the panic message includes the content of self.

Source

pub fn as_mut_param_spec(&mut self) -> Option<&mut &'a TypeParamParamSpec>

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

Source

pub fn expect_param_spec(self) -> &'a TypeParamParamSpec
where Self: Debug,

Panics if the value is not ParamSpec. In debug builds the panic message includes the content of self.

Source

pub fn param_spec(self) -> Option<&'a TypeParamParamSpec>

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