Struct UserStackMap

pub struct UserStackMap { /* private fields */ }

Expand description

A compiled stack map, describing the location of many GC-managed values.

A stack map is associated with a particular instruction, and that instruction is a safepoint.

Implementations§

impl UserStackMap

pub fn entries(&self) -> impl Iterator<Item = (Type, u32)>

Iterate over the entries in this stack map.

Yields pairs of the type of GC reference that is at the offset, and the offset from SP. If a pair (i64, 0x42) is yielded, for example, then when execution is at this stack map’s associated PC, SP + 0x42 is a pointer to an i64, and that i64 is a live GC reference.
