Struct Machine 

pub struct Machine {
    pub states: Vec<StateView>,
    pub transitions: Vec<TransitionView>,
    pub independent_of: Vec<String>,
}

The state machine as data, so that every surface projects the same machine instead of drawing its own.

use majordomus_cli::session::Machine;

let m = Machine::describe();
assert!(m.states.iter().filter(|s| s.terminal).count() == 1);
assert!(m.independent_of.iter().any(|note| note.contains("task")));

This is what session.machine answers. It exists because the same diagram is currently redrawn in docs/CONTINUITY.md, in lib/session.sh’s comments and in the Cockpit, and three drawings of one machine drift — the lib/session.sh one still had the task guard in it after ADR 0052 removed it from the code.

Fields

states: Vec<StateView>

Every state, with what it means and whether it is terminal.

transitions: Vec<TransitionView>

Every transition, with the states it runs between.

independent_of: Vec<String>

What the machine deliberately does not depend on, stated so that a reader does not have to infer an absence. One entry today: task state.

Implementations

impl Machine

pub fn describe() -> Self

The machine, derived from the two enums above and from nothing else.

use majordomus_cli::session::{EpisodeState, Machine, Transition};

let m = Machine::describe();
assert_eq!(m.states.len(), EpisodeState::ALL.len());
assert_eq!(m.transitions.len(), Transition::ALL.len());
assert!(m.states.iter().filter(|s| s.terminal).count() == 1, "one terminal state");
assert!(m.independent_of.iter().any(|s| s.contains("task")));

Trait Implementations

impl Clone for Machine

fn clone(&self) -> Machine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Machine

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Machine

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Machine

impl JsonSchema for Machine

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 Machine

fn eq(&self, other: &Machine) -> 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 Machine

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
