Struct AsmOperand 

pub struct AsmOperand {
    pub role: AsmRole,
    pub memory: bool,
    pub result: Option<Value>,
    pub value: Option<Value>,
    pub tied: Option<usize>,
}

One operand of an assembly statement, as its constraint describes it.

Fields

role: AsmRole

Which side of the colon it was written on.

memory: bool

Whether the assembly is handed the address of an object rather than a value.

result: Option<Value>

The result it produces, for an output that travels in a register.

value: Option<Value>

The value it reads, which every entry but a register output written = has.

An output written + is read as well as written, so it has both this and a result. An output in memory has this and no result, because what the assembly was handed is the address and the address is an operand like any other.

tied: Option<usize>

The output an input written as a number shares its place with.

"0" is the whole of what a matching constraint says: this input and that output are one place, so whatever the assembly leaves there is what the output gets.
