Struct ArrayPin 

pub struct ArrayPin {
    pub reg: u16,
    pub vec_slot: u16,
    pub ptr_slot: u16,
    pub len_slot: u16,
    pub elem: PinElem,
    pub mutated: bool,
}

Fields

reg: u16

vec_slot: u16

Frame slot receiving &mut Vec<…> as *mut _ as i64 — the handle the push helper extends through.

ptr_slot: u16

len_slot: u16

elem: PinElem

mutated: bool

This buffer is written IN PLACE (SetIndex) in a region that can take a recoverable side exit AND replays from the head on deopt (non-precise). Such a write is NOT replay-idempotent (a read-modify-write or swap would double-apply), so the VM snapshots this buffer’s full contents on region entry and restores them on a classic Deopt before replaying. Read-only buffers, push-only buffers (length truncate suffices), and precise regions (resume-at-op, no replay) leave this false.

Trait Implementations

impl Clone for ArrayPin

fn clone(&self) -> ArrayPin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrayPin

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

Formats the value using the given formatter.

impl PartialEq for ArrayPin

fn eq(&self, other: &ArrayPin) -> 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.
