Struct ExecutionContextHeader 

pub struct ExecutionContextHeader { /* private fields */ }

Pinned architecture header for one execution context.

CPU binding uses a four-phase publication word: Unbound -> Binding -> Bound -> Unbinding -> next Unbound. The epoch is retained solely to reject a stale incoming switch tail.

Implementations

impl ExecutionContextHeader

pub const fn new() -> Self

Creates an unbound header before placing it in stable pinned storage.

pub fn cpu_area(&self) -> Option<CpuAreaRef>

Returns the stable CPU area while this header is fully bound.

pub fn cpu_area_base(&self) -> Option<usize>

Returns the raw bound area base used by architecture trap entry.

pub fn as_non_null(self: Pin<&Self>) -> NonNull<Self>

Returns the stable pointer installed in the current-context source.

Trait Implementations

impl Default for ExecutionContextHeader

fn default() -> Self

Returns the “default value” for a type.
