Struct MemoryOpcode

pub struct MemoryOpcode { /* private fields */ }

Represents a full memory opcode: class, size, mode.

Implementations

impl MemoryOpcode

pub fn get_class(&self) -> &OpcodeClass

Returns the opcode’s class.

Example

use bpf_ins::{Instruction, Opcode, OpcodeClass, Register};

let instruction = Instruction::storex64(Register::R1, 0, Register::R2);
let opcode = instruction.get_opcode();
assert!(matches!(opcode, Opcode::Memory(_)));
if let Opcode::Memory(memory) = opcode {
    assert!(matches!(memory.get_class(), OpcodeClass::StoreReg));
}

pub fn get_size(&self) -> &MemoryOpSize

Returns the memory operation size.

Example

use bpf_ins::{Instruction, MemoryOpSize, Opcode, Register};

let instruction = Instruction::storex64(Register::R1, 0, Register::R2);
let opcode = instruction.get_opcode();
assert!(matches!(opcode, Opcode::Memory(_)));
if let Opcode::Memory(memory) = opcode {
    assert!(matches!(memory.get_size(), MemoryOpSize::DoubleWord));
}

pub fn get_mode(&self) -> &MemoryOpMode

Returns the memory operation mode.

Example

use bpf_ins::{Instruction, MemoryOpMode, Opcode, Register};

let instruction = Instruction::storex64(Register::R1, 0, Register::R2);
let opcode = instruction.get_opcode();
assert!(matches!(opcode, Opcode::Memory(_)));
if let Opcode::Memory(memory) = opcode {
    assert!(matches!(memory.get_mode(), MemoryOpMode::Memory));
}

Trait Implementations

impl Clone for MemoryOpcode

fn clone(&self) -> MemoryOpcode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryOpcode

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

Formats the value using the given formatter.

impl Ord for MemoryOpcode

fn cmp(&self, other: &MemoryOpcode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MemoryOpcode

fn eq(&self, other: &MemoryOpcode) -> 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 PartialOrd for MemoryOpcode

fn partial_cmp(&self, other: &MemoryOpcode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
