Trait Implementations

impl Clone for FnDecl

fn clone(&self) -> FnDecl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for FnDecl

fn eq(&self, __arg_0: &FnDecl) -> bool

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

fn ne(&self, __arg_0: &FnDecl) -> bool

This method tests for !=.
