Struct cranelift_codegen::machinst::sections::MachSectionSize

pub struct MachSectionSize {
    pub start_offset: CodeOffset,
    pub offset: CodeOffset,
}

A MachSectionOutput implementation that records only size.

Fields

start_offset: CodeOffset

The starting offset of this section.

offset: CodeOffset

The current offset of this section.

Methods

impl MachSectionSize

pub fn new(start_offset: CodeOffset) -> MachSectionSize

Create a new size-counting dummy section.

pub fn size(&self) -> CodeOffset

Return the size this section would take if emitted with a real sink.
