Struct PmiState 

pub struct PmiState {
    pub views: Vec<PmiView>,
    pub id_counter: u64,
}

The document’s pmi block.

Fields

views: Vec<PmiView>

id_counter: u64

Mints every view AND annotation id (VIEW{n}, DIM{n}, …); monotonic, never reused, re-seeded from the largest numeric suffix on load.

Implementations

impl PmiState

pub fn next_id(&mut self, prefix: &str) -> String

Mint the next id with prefix (VIEW → VIEW3). The counter is re-seeded first from the largest numeric suffix already in the block, so an edited or merged document never hands out a colliding id.

pub fn find_view(&self, id: &str) -> Option<&PmiView>

pub fn find_view_mut(&mut self, id: &str) -> Option<&mut PmiView>

pub fn find_annotation(&self, id: &str) -> Option<(&PmiView, &PmiAnnotation)>

The annotation with id and its owning view.

pub fn locate_annotation(&self, id: &str) -> Option<(usize, usize)>

The owning view id and index of annotation id.

pub fn find_annotation_mut(&mut self, id: &str) -> Option<&mut PmiAnnotation>

pub fn datum_letters(&self) -> Vec<(String, String)>

Every datum letter defined in the part (any view), in definition order, with the defining annotation’s id — the part-level datum registry a feature control frame validates its references against.

pub fn next_datum_letter(&self) -> Option<String>

The next unused datum letter: A–Z skipping I, O and Q (ASME Y14.5), then AA, AB, … (None only past ZZ).

pub fn is_empty(&self) -> bool

Whether the block carries anything worth persisting.
