Enum fastobo::ast::EntityFrame

pub enum EntityFrame {
    Typedef(Box<TypedefFrame>),
    Term(Box<TermFrame>),
    Instance(Box<InstanceFrame>),
}

An entity frame, describing either a term, an instance, or a typedef.

Ordering

Serializer conventions dictate that frames should be Serialized first with [Typedef] frames, then [Term], and then [Instance], which is reflected here in the order of the variants.

Variants

Typedef(Box<TypedefFrame>)

Term(Box<TermFrame>)

Instance(Box<InstanceFrame>)

Implementations

impl EntityFrame

pub fn as_term(&self) -> Option<&TermFrame>

Return a reference to the TermFrame if the entity frame is one, or None.

Use this function in conjunction with Iterator::flat_map to extract all term frames from an iterator of EntityFrame references:

let doc = fastobo::from_file("tests/data/ms.obo").unwrap();
let terms: Vec<&TermFrame> = doc
    .entities()
    .iter()
    .flat_map(EntityFrame::as_term)
    .collect();

pub fn as_term_mut(&mut self) -> Option<&mut TermFrame>

Return a mutable reference to the TermFrame if the entity frame is one, or None.

pub fn as_typedef(&self) -> Option<&TypedefFrame>

Return a reference to the TypedefFrame if the entity frame is one, or None.

pub fn as_typedef_mut(&mut self) -> Option<&mut TypedefFrame>

Return a mutable reference to the TypedefFrame if the entity frame is one, or None.

pub fn as_instance(&self) -> Option<&InstanceFrame>

Return a reference to the InstanceFrame if the entity frame is one, or None.

pub fn as_instance_mut(&mut self) -> Option<&mut InstanceFrame>

Return a mutable reference to the InstanceFrame if the entity frame is one, or None.

pub fn name(&self) -> Result<&UnquotedString, CardinalityError>

Get the name of the entity, if exactly one is declared.

pub fn definition(&self) -> Result<&Definition, CardinalityError>

Get the definition of the entity, if exactly one is declared.
