Crate rustc_data_structures
source · [−]Expand description
Various data structures used by the Rust compiler. The intention is that code in here should be not be specific to rustc, so that it can be easily unit tested and so forth.
Note
This API is completely unstable and subject to change.
Modules
Simple file-locking apis for each OS.
An immutable, owned value (except for interior mutability).
The
ObligationForest is a utility data structure used in trait
matching to track the set of outstanding obligations (those not yet
resolved to success or error). It also tracks the “backtrace” of each
pending obligation (why we are trying to figure this out in the first
place).An owning reference.
Rust Compiler Self-Profiling
This is a copy of
core::hash::sip adapted to providing 128 bit hashes.A utility class for implementing “snapshottable” things; a snapshottable data structure permits
you to take a snapshot (via
start_snapshot) and then, after making some changes, elect either
to rollback to the start of the snapshot or commit those changes.Calculation and management of a Strict Version Hash for crates
This module defines types which are thread safe if cfg!(parallel_compiler) is true.
This module implements tagged pointers.
A singly-linked list.
Module which contains the snapshot/rollback functionality of the
ena data structures.Union-find implementation. The main type is
UnificationTable.Macros
Type size assertion. The first argument is a type and the second argument is its expected size.
