Struct TransitionSpec 

pub struct TransitionSpec {
    pub from: Vec<Name>,
    pub except: Vec<Name>,
    pub to: Name,
    pub when: Cond<Name>,
    pub priority: i32,
    pub breaks_lock: bool,
    pub restart: bool,
}

A transition by names.

Fields

from: Vec<Name>

Source states; empty means any state.

except: Vec<Name>

With from empty: states it does not apply to.

to: Name

Target state.

when: Cond<Name>

When it fires.

priority: i32

Higher goes first.

breaks_lock: bool

Considered while the current state is locked.

restart: bool

May restart the state it starts from.

Implementations

impl TransitionSpec

pub fn new<S: Into<Name>>( from: impl IntoIterator<Item = S>, to: impl Into<Name>, when: Cond<Name>, ) -> Self

From any of from to to when when holds.

pub fn any(to: impl Into<Name>, when: Cond<Name>) -> Self

From any state to to when when holds.

pub fn except<S: Into<Name>>(self, states: impl IntoIterator<Item = S>) -> Self

Not from these states (with TransitionSpec::any).

pub fn priority(self, p: i32) -> Self

Set the priority.

pub fn breaks_lock(self) -> Self

Fire even while the current state is locked.

pub fn restart(self) -> Self

Allow restarting the current state.
