Struct InstanceOccurrence 

pub struct InstanceOccurrence { /* private fields */ }

Retains one occurrence’s identity, immediate parent, and local mapping ranges.

Parent/site pairs distinguish repeated uses of shared children. Root occurrences have neither a parent nor an inclusion site. No record owns another record.

use adam_rs::{Sheet, TemplateBuilder};
let template = TemplateBuilder::new().finish()?;
let instance = template.instantiate(&mut Sheet::new(), &[])?;
let root = &instance.occurrences()[0];
assert_eq!(root.template(), &template.id());
assert!(root.parent().is_none());
assert!(root.inclusion_site().is_none());
assert_eq!(instance.occurrence(root.id()).unwrap().id(), root.id());

Implementations

impl InstanceOccurrence

pub fn conditionals(&self) -> &[ConditionalId]

Borrows live conditional identities in this definition’s authored order.

These identities remain usable after the template is dropped.

Examples

let template = adam_rs::TemplateBuilder::new().finish()?;
let instance = template.instantiate(&mut adam_rs::Sheet::new(), &[])?;
assert!(instance.occurrences()[0].conditionals().is_empty());

pub fn id(&self) -> &OccurrenceId

Borrows this occurrence’s expansion-scoped identity.

Examples

See the occurrence example.

pub fn template(&self) -> &TemplateId

Borrows the identity of the expanded recipe.

Examples

See the occurrence example.

pub fn parent(&self) -> Option<&OccurrenceId>

Borrows the immediate parent identity, or returns None for the root.

Examples

See the occurrence example.

pub fn inclusion_site(&self) -> Option<&RelationshipSlot>

Borrows the inclusion group in the parent’s namespace, or returns None for the root.

Examples

See the occurrence example.

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

Formats the value using the given formatter.
