Struct Instruction

pub struct Instruction {
    pub pc: u32,
    pub opcode: Opcode,
    pub instruction: u32,
    /* private fields */
}

MIPS Instruction representation.

Do note that the fields may not always make sense as there are fields used by some instructions and some not used.

For example, the instruction Lw may have the value for rd set to RegisterType::A1, or RegisterType::T1 and it shouldn’t matter since that instruction only uses rs and rt. So keep that in mind when accessing the fields.

Fields

pc: u32

opcode: Opcode

instruction: u32
