Trait Implementations§

source§

impl Clone for CodeGenOptLevel

source§

fn clone(&self) -> CodeGenOptLevel

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl PartialEq for CodeGenOptLevel

source§

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