Struct Transition 

pub struct Transition {
    pub from: String,
    pub event: String,
    pub to: String,
    pub guard: Option<String>,
    pub actions: Vec<String>,
    pub description: Option<String>,
}

A transition between two states, triggered by an event.

Guards gate the transition; actions fire when the transition is taken. Both are string references resolved externally.

Fields

from: String

Source state name.

event: String

Event name that triggers this transition.

to: String

Target state name.

guard: Option<String>

Guard condition (string reference, resolved at runtime).

actions: Vec<String>

Side effects executed when transition fires (string references).

description: Option<String>

Description of what this transition represents.

Implementations

impl Transition

pub fn new( from: impl Into<String>, event: impl Into<String>, to: impl Into<String>, ) -> Self

Creates a new transition from source state to target state on event.

pub fn guard(self, guard: impl Into<String>) -> Self

Sets the guard condition (string reference).

pub fn actions(self, actions: Vec<impl Into<String>>) -> Self

Sets the transition actions (string references).

pub fn description(self, desc: impl Into<String>) -> Self

Sets the description.

Trait Implementations

impl Clone for Transition

fn clone(&self) -> Transition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Transition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Transition

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Transition

fn eq(&self, other: &Transition) -> 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 Serialize for Transition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
