Modules

tagging

Tag is a dynamically typed data structure used to encode extra properties about a type in its layout constant.

Structs

CompTLFunction	Equivalent to TLFunction,in which every field is a range into a TLFunctions.
Field1to1	Properties that are associated with all fields.
FieldIndex	An index composed of the (variant,field_position) pair.
FullType	The typename and generics of the type this layout is associated to, used for printing types.
GenericParams	Represents all the generic parameters of a type.
GetVariantNames	An iterator that yields the names of an enum's variants.
IncompatibleWithNonExhaustive	An error produced when checking that the Storage of a nonexhaustive enum is compatible with the enum.
IsExhaustive	Whether this enum is exhaustive,if it is,it can add variants in minor versions.
ItemInfo	Information about where a type was declared.
SliceAndFieldIndices	A slice of T,and a slice of ranges into the first slice,associating each range with a field.
StartLen	The start and length of a slice into TLFunctions.
TLEnum	The layout of an enum.
TLField	The layout of a field.
TLFields	The layout of a field.
TLFieldsIterator	An iterator over all the fields in a type definition.
TLFunction	A function pointer in a field.
TLFunctionRange	A slice of functions from a TLFunctions.
TLFunctions	A function pointer in a field.
TLNonExhaustive	Properties exclusive to nonexhaustive enums.
TLPrefixType	The definition of vtables and modules that can be extended in minor versions.
TypeLayout	The layout of a type, also includes metadata about where the type was defined.
TypeLayoutParams	The parameters for TypeLayout::from_params.
WithFieldIndex	A pair of (FieldIndex,T).

Enums

DiscriminantRepr	How the discriminant of an enum is represented.
FieldAccessor	Whether a field is accessible,and how it is accessed.
LifetimeIndex	Which lifetime is being referenced by a field. Allows lifetimes to be renamed,so long as the "same" lifetime is being referenced.
ModPath	A module path.
ReprAttr	The repr(..) attribute used on a type.
TLData	What kind of type this is.struct/enum/etc.
TLDataDiscriminant	A discriminant-only version of TLData.
TLDiscriminant	The discriminant of an enum variant.
TLDiscriminants	The discriminant of an enum variant.
TLFOSIter	A iterator over all the fields of a type definition.
TLFieldOrFunction	Either a TLField or a TLFunction.
TLFieldsOrSlice	Either a TLFields or a static slice of TLField.
TLPrimitive	Types defined in the compiler
