Implementations

impl<R> TypeParam<R>

pub const fn is_type_var(&self) -> bool

Returns true if self is of variant TypeVar.

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

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

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

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