Struct LabelOrOffset 

pub struct LabelOrOffset(/* private fields */);

A MachLabel or CodeOffset, bitpacked into a u32.

This type is used to represent a label reference in some MachBuffer metadata (specifically, relocations and exception-handler records). These start as labels before the MachBuffer is finalized; once finish() is called, they become code offsets.

Implementations

impl LabelOrOffset

pub fn label(label: MachLabel) -> Self

Create a LabelOrOffset that refers to a label.

pub fn offset(offset: CodeOffset) -> Self

Create a LabelOrOffset that refers to a code offset.

pub fn is_label(&self) -> bool

Is this a label?

pub fn is_offset(&self) -> bool

Is this a code offset?

pub fn as_label(&self) -> MachLabel

Unwrap as a label.

Panics

Panics if this is not a label.

pub fn as_offset(&self) -> CodeOffset

Unwrap as a code offset.

Panics

Panics if this is not a code offset.
