    StatePayload {
        state: &'static str,
        field_name: Option<&'static str>,
    },

    },
}

One exact relation source exported by the linked build.

Variants

StatePayload

A state payload type produced the relation.

Fields

state: &'static str

Source state that carries the relation.

field_name: Option<&'static str>

Named field for named payloads; None for tuple payloads.

MachineField

A machine struct field produced the relation.

Fields

field_name: Option<&'static str>

Named field for named structs; None for tuple structs.

field_index: usize

Stable field position within the machine struct.

TransitionParam

One transition parameter produced the relation.

Fields

state: &'static str

Source state where the transition is defined.

transition: &'static str

Transition method name.

param_index: usize

Stable non-receiver parameter index.

param_name: Option<&'static str>

Simple identifier name when available.

Trait Implementations

impl Clone for LinkedRelationSource

fn clone(&self) -> LinkedRelationSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinkedRelationSource

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

Formats the value using the given formatter.

impl PartialEq for LinkedRelationSource

fn eq(&self, other: &LinkedRelationSource) -> 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.
