Struct Session 

pub struct Session {
    pub sessionid: String,
    pub status: Status,
    pub configuration: StateSet,
    pub history: History,
    pub internal_queue: VecDeque<Event>,
    pub invocations: Vec<Invocation>,
    pub data_initialized: StateSet,
    pub send_counter: u64,
    pub invoke_counter: u64,
    pub macrosteps: u64,
    pub options: Options,
}

The state of one session, as a value.

The internal queue is part of the value: raise, send to #_internal and platform events (error.*, done.state.*) feed it, while external events arrive only as Inputs, so internal events are always processed before the next external one.

Fields

sessionid: String

_sessionid.

status: Status

Running or terminated.

configuration: StateSet

Active states (never the root).

history: History

Recorded history values.

internal_queue: VecDeque<Event>

The internal event queue.

invocations: Vec<Invocation>

Started, not yet cancelled invocations.

data_initialized: StateSet

States whose data items have been initialized (late binding); the root is set at start.

send_counter: u64

Counter for generated send identifiers.

invoke_counter: u64

Counter for generated invoke identifiers.

macrosteps: u64

Number of macrosteps completed.

options: Options

Options fixed at start.

Implementations

impl Session

pub fn is_terminated(&self) -> bool

Whether the session has ended.

pub fn active(&self, chart: &CompiledChart) -> Vec<String>

Active state identifiers in document order.

pub fn is_active(&self, chart: &CompiledChart, id: &str) -> bool

Whether the state with this identifier is active.

Trait Implementations

impl Clone for Session

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Session

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

Formats the value using the given formatter.

impl PartialEq for Session

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
