Enum cranelift_codegen::machinst::vcode::VCodeConstantData[][src]

pub enum VCodeConstantData {
    Pool(ConstantConstantData),
    WellKnown(&'static [u8]),
    Generated(ConstantData),
}

Identify the different types of constant that can be inserted into VCodeConstants. Tracking these separately instead of as raw byte buffers allows us to avoid some duplication.

Variants

A constant already present in the Cranelift IR ConstantPool.

WellKnown(&'static [u8])

A reference to a well-known constant value that is statically encoded within the compiler.

Generated(ConstantData)

A constant value generated during lowering; the value may depend on the instruction context which makes it difficult to de-duplicate–if possible, use other variants.

Implementations

impl VCodeConstantData[src]

pub fn as_slice(&self) -> &[u8]

Notable traits for &'_ [u8]
