Struct Condition 

pub struct Condition { /* private fields */ }

A signalled condition: a kind symbol plus a payload reference.

The condition system’s analogue of a raised exception, but resumable: the payload travels to the nearest matching ConditionHandler.

Implementations

impl Condition

pub fn new(kind: Symbol, payload: Ref) -> Self

Builds a condition of the given kind carrying payload.

pub fn kind(&self) -> &Symbol

Returns the condition kind used to select a handler.

pub fn payload(&self) -> &Ref

Returns the payload delivered to the handler.

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl Eq for Condition

impl PartialEq for Condition

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