add_fallible_state_machine

Generates a fallible state machine from a given state machine definition with error handling.

add_messages

Generates code to push messages into states or poll messages from states.

add_state_machine

Generates a state machine from a given state machine definition.

derive_state

Derives an empty implementation of the state.

derive_transition

Derives an empty transition of a transition from one state into another and allows to customise if it should always transit or never.

derive_transition_into

Derives an a implementation of the into trait for the transition if the target state does not contains any members

match_state_entry

Generate the enum entry of a state. Expects the name of the sfsm and the name (and type args) of the state as well as the desired name of the variable to work with as arguments. Can be used to generate match branches for example.

Attribute Macros

sfsm_trace

Creates a wrapper around a log function to forward the logs to. With the help of sfsm_trace, a logger function to which all logs from the state machine are forwarded to can be configured
