Struct DecodedInsn 

pub struct DecodedInsn {
    pub addr: VAddr,
    pub bytes: [u8; 8],
    pub kind: InsnKind,
    pub opcode: u8,
    pub dst: u8,
    pub src: u8,
    pub offset: i16,
    pub imm: i32,
    pub imm64: Option<u64>,
}

One decoded BPF slot.

Fields

addr: VAddr

bytes: [u8; 8]

kind: InsnKind

opcode: u8

dst: u8

Destination register (low nibble of byte 1).

src: u8

Source register (high nibble of byte 1).

offset: i16

16-bit signed offset, little-endian.

imm: i32

32-bit signed immediate, little-endian.

imm64: Option<u64>

Combined 64-bit immediate — populated only on the first slot of LDDW (opcode 0x18); None everywhere else.

Implementations

impl DecodedInsn

pub fn raw_u64(&self) -> u64

Raw 8-byte encoding interpreted as a u64 (little-endian).

Trait Implementations

impl ArchInsn for DecodedInsn

fn addr(&self) -> VAddr

Virtual address where this instruction lives.

fn original_bytes(&self) -> &[u8]

Exact bytes the instruction occupied in the source. Used by Function::emit_bytes to defend round-trip byte identity.

fn len_bytes(&self) -> usize

Length of the encoded instruction in bytes. Default impl uses original_bytes().len(); override only if your representation can differ between the two (e.g. a synthetic IR insn that doesn’t have a byte form yet).

impl Clone for DecodedInsn

fn clone(&self) -> DecodedInsn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodedInsn

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

Formats the value using the given formatter.

impl PartialEq for DecodedInsn

fn eq(&self, other: &DecodedInsn) -> 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.
