Struct Relocation 

pub struct Relocation {
    pub offset: usize,
    pub size: u8,
    pub label: Rc<str>,
    pub kind: RelocKind,
    pub addend: i64,
    pub trailing_bytes: u8,
}

A relocation record for unresolved labels.

Fields

offset: usize

Offset within the instruction bytes where the relocation target is.

size: u8

Size of the relocation field in bytes (1, 2, or 4).

label: Rc<str>

The label name to resolve. Stored as Rc<str> so that cloning during relocation propagation and linker resolution is a cheap refcount bump instead of a heap allocation.

kind: RelocKind

How the linker patches the target address into the instruction bytes.

addend: i64

The addend for the relocation (constant offset).

trailing_bytes: u8

Number of instruction bytes that follow the relocation field. For x86 RIP-relative relocations, the CPU computes EA = RIP + disp where RIP = address of the byte AFTER the entire instruction. When a trailing immediate follows the displacement, we need this to calculate the correct RIP at link time: rip = reloc_addr + size + trailing_bytes.

Trait Implementations

impl Clone for Relocation

fn clone(&self) -> Relocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relocation

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

Formats the value using the given formatter.
