Enum rustc_target::abi::Primitive

pub enum Primitive {
    Int(Integer, bool),
    Float(FloatTy),
    Pointer,
}

Fundamental unit of memory access and layout.

Variants

Int(Integer, bool)

The bool is the signedness of the Integer type.

One would think we would not care about such details this low down, but some ABIs are described in terms of C types and ISAs where the integer arithmetic is done on {sign,zero}-extended registers, e.g. a negative integer passed by zero-extension will appear positive in the callee, and most operations on it will produce the wrong values.

Float(FloatTy)Pointer

Trait Implementations

impl Clone for Primitive

fn clone(&self) -> Primitive

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Primitive> for Primitive

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