Modules

[Unstable]

This module provides a simplified abstraction for working with code blocks identified by their integer node-id. In particular, it captures a common set of attributes that all "function-like things" (represented by FnLike instances) share. For example, all FnLike instances have a type signature (be it explicit or inferred). And all FnLike instances have a body, i.e. the code that is run when the function-like thing it represents is invoked.

definitions [Unstable]

Structs

DefKey	[Unstable] A unique identifier that we can use to lookup a definition precisely. It combines the index of the definition's parent (if any) with a `DisambiguatedDefPathData`.
DefPath	[Unstable]
Definitions	[Unstable] The definition table containing node definitions
DisambiguatedDefPathData	[Unstable] Pair of `DefPathData` and an integer disambiguator. The integer is normally 0, but in the event that there are multiple defs with the same `parent` and `data`, we use this field to disambiguate between them. This introduces some artificial ordering dependency but means that if you have (e.g.) two impls for the same type in the same module, they do get distinct def-ids.
Forest	[Unstable] Stores a crate and any number of inlined items from other crates.
InlinedRootPath	[Unstable] Root of an inlined item. We track the `DefPath` of the item within the original crate but also its def-id. This is kind of an augmented version of a `DefPath` that includes a `DefId`. This is all sort of ugly but the hope is that inlined items will be going away soon anyway.
Map	[Unstable] Represents a mapping from Node IDs to AST elements and their parent Node IDs
NodesMatchingSuffix	[Unstable]

Enums

DefPathData	[Unstable]
MapEntry	[Unstable] Represents an entry and its parent NodeID. The odd layout is to bring down the total size.
Node	[Unstable]

Traits

FoldOps	[Unstable]
NodePrinter	[Unstable]

Functions

collect_definitions	[Unstable]
map_crate	[Unstable]
map_decoded_item	[Unstable] Used for items loaded from external crate that are being inlined into this crate.
