Changed

• Add a new type parameter to spsc::Queue that indicates whether the queue is only single-core safe, or multi-core safe. By default the queue is multi-core safe; this preserves the current semantics. New unsafe constructors have been added to create the single-core variant.

v0.4.0 - 2018-10-19

Changed

• This crate now compiles on stable when both the "const-fn" and "smaller-atomics" features are disabled.

Fixed

• The RingBuffer.len function
• Compilation on recent nightlies

v0.3.6 - 2018-05-04

v0.3.1 - 2018-04-23

Added

• Fixed capacity implementations of IndexMap and IndexSet.
• A Extend implementation to Vec
• More PartialEq implementations to Vec

v0.3.0 - 2018-04-22

Changed

• [breaking-change] The capacity of all data structures must now be specified using type level integers (cf. typenum). See documentation for details.

• [breaking-change] BufferFullError has been removed in favor of (a) returning ownership of the item that couldn't be added to the collection (cf. Vec.push), or (b) returning the unit type when the argument was not consumed (cf. Vec.extend_from_slice).

Added

• Unchecked methods to dequeue and enqueue items into a RingBuffer via the Consumer and Producer end points.

v0.2.6 - 2018-04-18

Added

• A BinaryHeap implementation. BinaryHeap is a priority queue implemented with a binary heap.

v0.2.5 - 2018-04-13

• [breaking-change] The error type of all operations that may fail has changed from () to BufferFullError.

• Both RingBuffer and Vec now support arrays of any size for their backup storage.

[v0.1.0] - 2017-04-27
