class sun::types::ReferenceType : public sun::types::Type

Reference type - behaves like a pointer but with implicit dereferencing Type annotation: ref(T) where T is the referenced type Examples: ref(i32) = reference to i32 When reading a reference, it automatically dereferences When assigning to a reference, it stores to the underlying address.

equals

public · function · Source (opens in a new tab)

bool sun::types::ReferenceType::equals(const Type &other) const override

Reports whether the other type has the same semantic identity.

getClassLifetimeArgs

public · function · Source (opens in a new tab)

const std::vector< std::string > & sun::types::ReferenceType::getClassLifetimeArgs() const

Lifetime arguments applied to the referent's class ('ref Bus<'this>'): positionally binding the class's declared lifetimes.

Metadata like lifetimeName_ - never part of the type's identity.

void sun::types::ReferenceType::setLifetimeName(std::string name)

Assigns the named lifetime associated with the borrowed value.

toDisplayString
