sourcepub fn is_vmgcref_type(&self) -> bool
pub fn is_vmgcref_type(&self) -> bool
Is this a type that is represented as a VMGcRef
?
sourcepub fn is_vmgcref_type_and_not_i31(&self) -> bool
pub fn is_vmgcref_type_and_not_i31(&self) -> bool
Is this a type that is represented as a VMGcRef
and is additionally
not an i31
?
That is, is this a a type that actually refers to an object allocated in a GC heap?
