Struct Patch

pub struct Patch { /* private fields */ }

A section patch. Patches are bytes (or groups of bytes) whose computation was deferred to the linker.

Implementations

impl Patch

pub fn source(&self) -> (u32, u32)

Where the patch was defined. That is, the file stack node ID, and the line number.

pub fn offset(&self) -> u32

The offset within the section’s data where the patch will be written.

pub fn patch_type(&self) -> PatchType

The patch’s type, which notably determines its size.

pub fn pc_section_id(&self) -> u32

The ID of the expression’s PC section. See pc_offset for more info.

pub fn pc_offset(&self) -> u32

The expression’s PC offset.

This is separate from the offset, because PC (@) may not point to the byte being written, and, in the case of LOAD blocks, may be in a different section entirely!

pub fn expr(&self) -> &RpnExpr

The patch’s RPN expression.
