Trait Implementations

impl Clone for TransitionValue

fn clone(&self) -> TransitionValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransitionValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransitionValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TransitionValue

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

Formats the value using the given formatter.

impl FromStr for TransitionValue

type Err = FromStrError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for TransitionValue

fn eq(&self, other: &TransitionValue) -> 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 Sequence for TransitionValue

const CARDINALITY: usize

Number of values of type Self.

fn next(&self) -> Option<Self>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<Self>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<Self>

Returns the first value of type Self.

fn last() -> Option<Self>

Returns the last value of type Self.

impl Serialize for TransitionValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
