Struct MachCallSite 

pub struct MachCallSite {
    pub ret_addr: CodeOffset,
    pub frame_offset: Option<u32>,
    /* private fields */
}

A call site record resulting from a compilation.

Fields

ret_addr: CodeOffset

The offset of the call’s return address, relative to the start of the buffer.

frame_offset: Option<u32>

The offset from the FP at this callsite down to the SP when the call occurs, if known. In other words, the size of the stack frame up to the saved FP slot. Useful to recover the start of the stack frame and to look up dynamic contexts stored in ExceptionContextLoc::SPOffset.

If None, the compiler backend did not specify a frame offset. The runtime in use with the compiled code may require the frame offset if exception handlers are present or dynamic context is used, but that is not Cranelift’s concern: the frame offset is optional at this level.

Trait Implementations

impl Clone for MachCallSite

fn clone(&self) -> MachCallSite

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MachCallSite

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MachCallSite

fn eq(&self, other: &MachCallSite) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
