Struct Instruction

pub struct Instruction {
    pub opcode: Opcode,
    pub address: Gs2BytecodeAddress,
    pub operand: Option<Operand>,
}

Represents an instruction in a bytecode system.

Fields

opcode: Opcode

The opcode of the instruction.

address: Gs2BytecodeAddress

The address of the instruction.

operand: Option<Operand>

The operand of the instruction, if any.

Implementations

impl Instruction

pub fn new(opcode: Opcode, address: usize) -> Self

Create a new Instruction.

Arguments

• opcode: The opcode of the instruction.
• address: The address of the instruction.

Returns

• A new Instruction instance.

pub fn new_with_operand( opcode: Opcode, address: usize, operand: Operand, ) -> Self

Create a new Instruction with an operand.

Arguments

• opcode: The opcode of the instruction.
• address: The address of the instruction.
• operand: The operand of the instruction.

Returns

• A new Instruction instance.

pub fn set_operand(&mut self, operand: Operand)

Set the operand of the instruction.

Arguments

• operand: The operand to set.

Example

use gbf_core::instruction::Instruction;
use gbf_core::operand::Operand;
use gbf_core::opcode::Opcode;

let mut instruction = Instruction::new(Opcode::PushNumber, 0);
instruction.set_operand(Operand::new_number(42));

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Instruction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Instruction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Instruction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Instruction

Implement the Display trait for Instruction.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Convert the Instruction to a string

Returns

• A string representation of the instruction.

Example

use gbf_core::instruction::Instruction;
use gbf_core::operand::Operand;
use gbf_core::opcode::Opcode;

let instruction = Instruction::new_with_operand(Opcode::PushNumber, 0, Operand::new_number(42));
let string = instruction.to_string();
assert_eq!(string, "PushNumber 0x2a");

impl Hash for Instruction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Instruction

fn eq(&self, other: &Instruction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Instruction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Instruction
