Struct StageStateRef 

pub struct StageStateRef<Msg, St> { /* private fields */ }

A handle for sending messages to a stage via the Effects argument to the stage transition function.

This is a variant that is mostly useful in tests because it allows extracting the current state of the stage.

Implementations

impl<Msg, St> StageStateRef<Msg, St>

pub fn without_state(self) -> StageRef<Msg>

Methods from Deref<Target = StageRef<Msg>>

pub fn name(&self) -> &Name

Trait Implementations

impl<Msg, St> AsRef<StageRef<Msg>> for StageStateRef<Msg, St>

fn as_ref(&self) -> &StageRef<Msg>

Converts this type into a shared reference of the (usually inferred) input type.

impl<Msg, St> Clone for StageStateRef<Msg, St>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Msg, St> Debug for StageStateRef<Msg, St>

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

Formats the value using the given formatter.

impl<Msg, St> Deref for StageStateRef<Msg, St>

type Target = StageRef<Msg>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de, Msg, St> Deserialize<'de> for StageStateRef<Msg, St>

where Msg: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Msg: PartialEq, St: PartialEq> PartialEq for StageStateRef<Msg, St>

fn eq(&self, other: &StageStateRef<Msg, St>) -> 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<Msg, St> Serialize for StageStateRef<Msg, St>

where Msg: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
