Struct ExportState 

pub struct ExportState {
    pub index: usize,
    pub rust_name: &'static str,
    pub label: Option<&'static str>,
    pub description: Option<&'static str>,
    pub has_data: bool,
    pub is_root: bool,
}

State metadata preserved in the stable export surface.

Fields

index: usize

Stable export-local state index.

rust_name: &'static str

Rust variant name emitted by Statum.

label: Option<&'static str>

Optional human-facing label from presentation metadata.

description: Option<&'static str>

Optional human-facing description from presentation metadata.

has_data: bool

Whether the state carries state_data.

is_root: bool

Whether the state has no incoming edge in the exported topology.

Implementations

impl ExportState

pub fn node_id(&self) -> String

Stable renderer node id for this state.

pub fn display_label(&self) -> Cow<'static, str>

Human-facing state label used by text renderers.

Trait Implementations

impl Clone for ExportState

fn clone(&self) -> ExportState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExportState

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

Formats the value using the given formatter.

impl PartialEq for ExportState

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
