Struct frenetic::Context

#[repr(transparent)]pub struct Context(_);

A CPU context

This structure holds the non-volatile state in the platform's calling convention.

Implementations

impl Context

pub fn wipe()

Clear all basic volatile registers and CPU flags

#[must_use]pub fn save(&mut self) -> bool

Saves the non-volatile registers

NOTE: This function can return more than once.

This function returns true when returning locally from a save() operation and returns false when returning remotely from a load() operation.

pub unsafe fn load(&self) -> !

Load a context

This function stops executing at the current location and resumes execution wherever Self::save() was called (with a false return value).

Safety

This is very unsafe. You MUST have called Self::save() before calling this function. Further, all the pointers in the non-volatile registers must still be valid.

Trait Implementations

impl Default for Context

fn default() -> Context

Returns the "default value" for a type.
