Modules

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

Structs

CompFieldAccessor	A compressed field accessor,represented as 3 bits inside of a CompTLField.
CompGenericParams	The compressed generic parameters of a type, which can be expanded into a GenericParams by calling expand.
CompTLField	A TLField represented as a u64,expanded to a TLField by calling the expand method.
CompTLFields	The layout of all compressed fields in a type definition, one can access the expanded fields by calling the expand method.
CompTLFunction	A compressed version of a function pointer type, which can be expanded into a TLFunction by calling the expand method.
FmtFullType	The typename and generics of the type this layout is associated to, used for printing types (eg: `RVec<u8>` ).
GenericParams	The generic parameters of a type.
GenericTLEnum	The layout of an enum,that might depend on generic parameters.
GenericTLPrefixType	Properties of prefix types (vtables and modules) that depends on generic parameters.
IncompatibleWithNonExhaustive	An error declaring that the Storage of a nonexhaustive enum is not 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.
LifetimeIndex	Which lifetime is being referenced by a field. Allows lifetimes to be renamed,so long as the "same" lifetime is being referenced.
LifetimeIndexArray	A `LifetimeIndex::NONE` terminated array of 5 lifetime indices.
LifetimeIndexPair	A pair of `LifetimeIndex`.
LifetimeRange	Either a `LifetimeArray` or a range into a slice of `LifetimePair`s.
MTLIterator	An iterator over a list of `TypeLayoutCtor`.
MismatchedTLDataVariant	An error returned by MonoTLData::expand because the GenericTLData it tried to combine itself with was a different variant.
ModPath	A module path.
MonoSharedVars	a few static slices that many types in the `type_layout` module contain ranges into, requiring this type to be passed as a parameter.
MonoTLEnum	The parts of the layout of an enum,that don't depend on generic parameters.
MonoTLPrefixType	Properties of prefix types (vtables and modules) that don't change with generic parameters.
MonoTypeLayout	The data in the type layout that does not depend on generic parameters.
MultipleTypeLayouts	This stores multiple `TypeLayoutCtor`,some inline and some in a borrowed slice.
OptionU8	An optional u8 which represents None as `u8::max_value()`
OptionU16	An optional u16 which represents None as `u16::max_value()`
SharedVars	a few static slices that many types in the `type_layout` module contain ranges into, requiring this type to be passed as a parameter.
StartLen	The start and length of a slice into `TLFunctions`.
StartLenConverter	Used to convert the stuff passed to the `tl_genparams` macro to a `StartLen`.
TLDiscriminants	The discriminants of an enum.
TLEnum	Every property about an enum specifically.
TLField	The layout of a field.
TLFields	The layout of all field in a type definition.
TLFieldsIterator	An iterator over all the fields in a type definition.
TLFunction	A function pointer in a field.
TLFunctionIter	An iterator over a range of `TLFunction`s.
TLFunctionSlice	A slice of functions from a TLFunctions.
TLFunctions	All the function pointer types in a type declaration.
TLNonExhaustive	Properties exclusive to nonexhaustive enums.
TLPrefixType	Properties of prefix types (vtables and modules), combining `MonoTLPrefixType` and `GenericTLPrefixType`.
TypeLayout	The layout of a type, also includes metadata about where the type was defined.
TypeLayoutIndex	An index into the slice of `TypeLayoutCtor` for the type,
TypeLayoutRange	A range of indices into the slice of `TypeLayoutCtor` in the SharedVars for the type, which can store up to 4 indices inline, requiring additional `TypeLayoutCtor` to be stored contiguously after the fourth one in the slice.

Enums

DiscriminantRepr	How the discriminant of an enum is represented.
FieldAccessor	Whether a field is accessible,and how it is accessed.
GenericTLData	The part of TLData that can change based on generic parameters.
LifetimeArrayOrSlice	Either an array of 3 `LifetimeIndexPair`,or a slice of `LifetimeIndexPair`.
MonoTLData	The parts of TLData that don't change based on generic parameters.
ReprAttr	The `repr(..)` attribute used on a type.
TLData	The interior of the type definition, describing whether the type is a primitive/enum/struct/union and its contents.
TLDataDiscriminant	A discriminant-only version of TLData.
TLDiscriminant	A discriminant of an enum variant.
TLFieldOrFunction	Either a TLField or a TLFunction.
TLPrimitive	Types defined in the compiler

Type Definitions

CompTLFieldRepr	The underlying representation of CompTLField.
LifetimeIndexPairRepr	The representation of a `LifetimeIndexPair`.
StartLenRepr	The internal representation of StartLen.
