Method end_patchable

cranelift/codegen/src/machinst/buffer.rs:625–631

End a region of patchable code, yielding a [`PatchRegion`] value that can be consumed later to produce a one-off mutable slice to the associated region of the data buffer.

(&mut self, open: OpenPatchRegion)

    /// can be consumed later to produce a one-off mutable slice to the
    /// associated region of the data buffer.
    pub fn end_patchable(&mut self, open: OpenPatchRegion) -> PatchRegion {
        // No need to assert the state of `open_patchable` here, as we take
        // ownership of the only `OpenPatchable` value.
        self.open_patchable = false;
        let end = usize::try_from(self.cur_offset()).unwrap();
        PatchRegion { range: open.0..end }
    }

    /// Allocate a `Label` to refer to some offset. May not be bound to a fixed
    /// offset yet.
