Struct Instruction

pub struct Instruction<T: Debug> {
    pub op_code: usize,
    pub name: String,
    pub arity: usize,
    pub fun: InstructionFn<T>,
}

Describes a single instruction which can be used to execute programs.

Contains:

• An op code - a unique integer to identify this instruction.
• A name for serialisation and debugging reasons.
• An arity - the number of arguments this instruction expects to receive.
• A function which is used to execute the instruction.

Fields

op_code: usize

name: String

arity: usize

fun: InstructionFn<T>

Implementations
