Struct PatchableSite 

pub struct PatchableSite { /* private fields */ }

Self-describing handle for a patchable displacement (jump/call).

Implementations

impl PatchableSite

pub const unsafe fn new(offset: CodeOffset, kind: LabelUse, addend: i64) -> Self

Construct a site handle manually.

Safety

offset in any image you later patch must be a valid displacement field of kind with the same layout as when the site was emitted or recorded.

pub const fn offset(self) -> CodeOffset

pub const fn kind(self) -> LabelUse

pub const fn addend(self) -> i64

pub unsafe fn retarget( self, bytes: &mut [u8], target_offset: CodeOffset, ) -> Result<(), AsmError>

Retarget this site in a mutable code image.

Safety

bytes must be the code image this site was recorded against (same layout). The caller synchronizes concurrent execution of the patched region.
