Trait Implementations§

source§

impl Clone for ParamTag

source§

fn clone(&self) -> ParamTag

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 Tag for ParamTag

source§

const BITS: u32 = 1u32

Turns this tag into an integer. Read more
source§

unsafe fn from_usize(tag: usize) -> Self

Re-creates the tag from the integer returned by into_usize. Read more

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
