Methods

impl Pat

pub fn to_ty(&self) -> Option<P<Ty>>

Attempt reparsing the pattern as a type. This is intended for use by diagnostics.

pub fn walk(&self, it: &mut impl FnMut(&Pat) -> bool)

Walk top-down and call it in each place where a pattern occurs starting with the root pattern walk is called on. If it returns false then we will descend no further but siblings will be processed.

pub fn is_rest(&self) -> bool

Is this a .. pattern?
