Struct GraphSpec 

pub struct GraphSpec {
    pub params: Vec<(Name, ParamKind)>,
    pub states: Vec<StateSpec>,
    pub transitions: Vec<TransitionSpec>,
    pub entry: Option<Name>,
}

A whole graph by names.

Fields

params: Vec<(Name, ParamKind)>

Declared parameters.

states: Vec<StateSpec>

The states; the first is the entry unless GraphSpec::entry says otherwise.

transitions: Vec<TransitionSpec>

The transitions.

entry: Option<Name>

The starting state’s name; None: the first state.

Implementations

impl GraphSpec

pub fn new() -> Self

An empty spec.

pub fn bool(self, name: impl Into<Name>) -> Self

Declare a bool parameter.

pub fn float(self, name: impl Into<Name>) -> Self

Declare a float parameter.

pub fn trigger(self, name: impl Into<Name>, ttl: f32) -> Self

Declare a trigger that waits ttl seconds to be consumed.

pub fn state(self, s: StateSpec) -> Self

Add a state.

pub fn transition(self, t: TransitionSpec) -> Self

Add a transition.

pub fn entry(self, name: impl Into<Name>) -> Self

Start in the state name.

pub fn compile(&self) -> Result<Graph, SpecError>

Resolve names, check kinds, order transitions by priority.
