Struct DeoptInfo 

#[repr(C)]
pub struct DeoptInfo {
    pub resume_ip: usize,
    pub frame_count: usize,
    pub stack_count: usize,
    pub frames: [DeoptFrame; 4],
    pub stack_buf: [i64; 32],
    pub stack_kinds: [u8; 32],
}

Out-parameter the trace fn writes on every invocation.

resume_ip is set by the trace on every exit (normal loop fallthrough OR side-exit). frame_count is 0 for caller-frame side-exits (no materialization needed) and 1..=MAX_DEOPT_FRAMES for callee-frame side-exits. stack_count is the number of abstract-stack values the trace had built up at the side-exit; the VM pushes them onto vm.stack after the trace returns, materializing each entry as Value::Int or Value::Float based on the parallel stack_kinds tag (Float values are bit-cast through f64::from_bits).

Fields

resume_ip: usize

Bytecode IP the interpreter should resume at (set on every trace exit — normal fallthrough and side-exit alike).

frame_count: usize

Number of materialised callee frames in frames (0 for caller-frame side-exits, 1..=MAX_DEOPT_FRAMES for callee).

stack_count: usize

Number of abstract-stack entries in stack_buf to push onto vm.stack after the trace returns.

frames: [DeoptFrame; 4]

Callee frame snapshots (slot vectors + return IPs) for the VM to restore. Slots 0..frame_count are valid.

stack_buf: [i64; 32]

Raw bit pattern for each abstract-stack entry; reinterpret as i64 or f64 based on stack_kinds[i].

stack_kinds: [u8; 32]

Per-entry tag for stack_buf: STACK_KIND_INT or STACK_KIND_FLOAT.
