Struct Restart 

pub struct Restart { /* private fields */ }

A named recovery point: a symbol bound to a captured continuation.

The condition system’s restart: invoking it resumes the underlying ContinuationValue with a supplied value, returning control to the point where the restart was established.

Implementations

impl Restart

pub fn new(name: Symbol, continuation: ContinuationValue) -> Self

Binds name to the recovery continuation.

pub fn name(&self) -> &Symbol

Returns the restart name.

pub fn continuation(&self) -> &ContinuationValue

Returns the continuation this restart resumes.

pub fn invoke(&self, cx: &mut Cx, value: Ref) -> Result<ControlResultValue>

Invokes the restart, resuming its continuation with value and returning the resulting ControlResultValue.

Trait Implementations

impl Clone for Restart

fn clone(&self) -> Restart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Restart

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

Formats the value using the given formatter.

impl Eq for Restart

impl PartialEq for Restart

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