Enum SourceKind 

pub enum SourceKind {
    None,
    Temporary(u8),
    Input,
    Constant,
}

What a source operand reads.

Variants

None

No register: the operand is unused (register type 0).

Temporary(u8)

A temporary register R<n>, 0 to 31.

Input

A vertex attribute: the instruction’s one input index (v[n]), or that index plus the address register where Instruction::input_relative is set.

Constant

A float constant: the instruction’s one constant index (c[n]), or that index plus the address register where Instruction::constant_relative is set.
