Term

Enum Term 

Source
pub enum Term {
    Root,
    Arg(u8),
    Deep(u8, u8),
    Reg(Value),
    Num(i128),
}
Expand description

One node of the term the matcher is walking.

A position rather than a term, because the term does not exist. Two of these are values in their own right, and they are the two a pattern can bind: the register a value wraps and the number an iconst wraps.

Variants§

§

Root

The instruction being selected.

§

Arg(u8)

Operand i of the root, shown the way the plan says to show it.

§

Deep(u8, u8)

Operand j of the instruction that computed operand i of the root.

§

Reg(Value)

A value in a register, which is what a pattern binds when it writes (value.iN x).

§

Num(i128)

A constant, which is what a pattern binds or tests inside an (iconst.iN k).
