Struct RecTypeRef 

pub struct RecTypeRef { /* private fields */ }

A self-contained reference to one definition of a recursive group.

This is what makes a recursive Type stand alone: the whole group travels with the reference, so layout, unfolding, equality, hashing, and serialization all work without any external context.

Implementations

impl RecTypeRef

pub fn name(&self) -> Option<Arc<str>>

The declared name of the aggregate this reference selects, if it has one.

This agrees with the name on the unfolded form, so the folded and unfolded views of a recursive aggregate never disagree about what it is called.

pub fn kind(&self) -> AggregateKind

Whether this reference selects a struct or an enum definition.

pub fn layout(&self) -> TypeLayout

The cached layout of the selected definition.

pub fn group_len(&self) -> usize

The number of definitions in this reference’s group.

A group larger than one definition is mutually recursive.
