Enum ControlFlow

pub enum ControlFlow {
    Continue,
    Break,
}

Continue calling the closure in the future iterations or drop it.

This is the return type of idle_add and timeout_add closures.

ControlFlow::Continue keeps the closure assigned, to be rerun when appropriate.

ControlFlow::Break disconnects and drops it.

Continue and Break map to G_SOURCE_CONTINUE (true) and G_SOURCE_REMOVE (false), respectively.

Variants

Continue

Break

Implementations

impl ControlFlow

pub fn is_continue(&self) -> bool

Returns true if this is a Continue variant.

pub fn is_break(&self) -> bool

Returns true if this is a Break variant.

Trait Implementations

impl Clone for ControlFlow

fn clone(&self) -> ControlFlow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ControlFlow

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

Formats the value using the given formatter.

impl From<ControlFlow<()>> for ControlFlow

fn from(c: ControlFlow<()>) -> Self

Converts to this type from the input type.

impl From<ControlFlow> for ControlFlow<()>

fn from(c: ControlFlow) -> Self

Converts to this type from the input type.

impl From<ControlFlow> for Value

fn from(v: ControlFlow) -> Self

Converts to this type from the input type.

impl From<ControlFlow> for bool

fn from(c: ControlFlow) -> Self

Converts to this type from the input type.

impl From<bool> for ControlFlow

fn from(c: bool) -> Self

Converts to this type from the input type.

impl PartialEq for ControlFlow

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

impl ToValue for ControlFlow

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl Copy for ControlFlow
