Implementations

impl MonoTypeLayout

pub fn name(&self) -> &'static str

Gets the name of the type.

pub const fn repr_attr(&self) -> ReprAttr

Gets the representation attribute of the type.

pub const fn mod_refl_mode(&self) -> ModReflMode

Gets the ModReflMode for the type, whether this is a module whose definition can be reflected on at runtime.

pub const fn item_info(&self) -> &ItemInfo

Gets information about where a type was declared.

pub const fn shared_vars(&self) -> &MonoSharedVars

Gets the SharedVars of the type, containing the slices that many types inside TypeLayout contain ranges into.

pub const fn shared_vars_static(&'static self) -> &'static MonoSharedVars

Gets the SharedVars of the type, containing the slices that many types inside TypeLayout contain ranges into.

This was defined as a workaround for an internal compiler error in nightly.

pub fn get_fields(&self) -> Option<CompTLFields>

Gets the compressed versions of 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.

pub fn field_names(
&self
) -> impl ExactSizeIterator<Item = &'static str> + Clone + 'static

Gets an iterator over all the names of the fields in the type.

pub fn get_field_name(&self, nth: usize) -> Option<&'static str>

Gets the name of the nth field in the type. Returns None if there is no nth field.
