Crate rustc_data_structures

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

base_n
bit_set
const_cstr
fingerprint
flock	Simple file-locking apis for each OS.
fx
graph
indexed_vec
interner
macros
obligation_forest	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).
owning_ref	An owning reference.
ptr_key
sip128	This is a copy of core::hash::sip adapted to providing 128 bit hashes.
small_c_str
snapshot_map
snapshot_vec	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.
sorted_map
stable_hasher
svh	Calculation and management of a Strict Version Hash for crates
sync	This module defines types which are thread safe if cfg!(parallel_compiler) is true.
thin_vec
tiny_list	A singly-linked list.
transitive_relation
unify	Union-find implementation. The main type is UnificationTable.
vec_linked_list
work_queue

Macros

const_cstr	This macro creates a zero-overhead &CStr by adding a NUL terminator to the string literal passed into it at compile-time. Use it like:
impl_stable_hash_via_hash
likely
newtype_index	Creates a struct type S that can be used as an index with IndexVec and so on.
parallel
rustc_erase_owner
static_assert	A simple static assertion macro. The first argument should be a unique ALL_CAPS identifier that describes the condition.
unlikely

Structs

OnDrop

Traits

ToHex

A trait for converting a value to hexadecimal encoding
