Struct abi_stable::type_layout::TypeLayout [−][src]
#[repr(C)]pub struct TypeLayout { /* fields omitted */ }Expand description
The layout of a type, also includes metadata about where the type was defined.
Implementations
Gets the SharedVars of the type, containing the slices that many types inside TypeLayout contain ranges into.
Gets the package and package version where the type was declared.
Gets the package version for the package where the type was declared.
Gets a trait object used to check extra properties about the type.
Gets the fields of the type.
Return value
If this a:
-
primitive or opaque type: It returns
None. -
enum: It returns
Some()with all the fields in the order that they were declared, ignoring variants. -
structs/unions/prefix types: It returns
Some()with all the fields in the order that they were declared.
Whether this is a prefix-type(module or vtable).
Gets whether the type is a NonZero type,
which can be put in an Option while being ffi-safe.
Gets the UTypeId for the type,
which is an ffi safe equivalent of TypeId.
Gets the Tag associated with a type,
a JSON-like datastructure which is another way to
check extra properties about a type.
Gets the ModReflMode for the type,
whether this is a module whose definition can be reflected on at runtime.
The interior of the type definition, describing whether the type is a primitive/enum/struct/union and its contents.
Describes whether the type is a primitive/enum/struct/union,
every variant corresponds to a TLData variant of the same name.
Gets the virtual fields that aren’t part of th type definition, but are checked as part of the type
Gets the generic parameters of the type.
Gets the parts of the type layout that don’t change with generic parameters.
