Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

v0.4.1 - 2018-12-16

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

• [breaking-change] All Cargo features are disabled by default. This crate now compiles on stable by default.

• [breaking-change] RingBuffer has been renamed to spsc::Queue. The ring_buffer module has been renamed to spsc.

• [breaking-change] The bounds on spsc::Queue have changed.

Removed

• [breaking-change] The sealed Uxx trait has been removed from the public API.

v0.3.7 - 2018-08-19

Added

• Implemented IntoIterator and FromIterator for Vec
• ready methods to ring_buffer::{Consumer,Producer}
• An opt-out "const-fn" Cargo feature that turns const functions into normal functions when disabled.
• An opt-out "smaller-atomics" Cargo feature that removes the ability to shrink the size of RingBuffer when disabled.

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

Fixed

• The capacity of RingBuffer. It should be the requested capacity plus not twice that plus one.

v0.3.5 - 2018-05-03

Added

• RingBuffer.enqueue_unchecked an unchecked version of RingBuffer.enqueue

v0.3.4 - 2018-04-28

Added

• BinaryHeap.pop_unchecked an unchecked version of BinaryHeap.pop

v0.3.3 - 2018-04-28

Added

• BinaryHeap.push_unchecked an unchecked version of BinaryHeap.push

v0.3.2 - 2018-04-27

Added

• A re-export of generic_array::ArrayLength, for convenience.

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).

v0.2.7 - 2018-04-20

Added

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

Changed

• RingBuffer now has a generic index type, which default to usize for backward compatibility. Changing the index type to u8 or u16 reduces the footprint of the RingBuffer but limits its maximum capacity (254 and 65534, respectively).

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

Fixed

• Dereferencing heapless::Vec no longer incurs in a bounds check.

v0.2.4 - 2018-03-12

Fixed

• LinerMap::new is now a const fn

v0.2.3 - 2018-03-11

Added

• A swap_remove method to Vec
• A LinearMap implementation. LinearMap is a map / dict backed by an array and that performs lookups via linear search.

v0.2.2 - 2018-03-01

Added

• Fixed size version of std::String

v0.2.1 - 2017-12-21

Added

• Vec now implements both fmt::Debug, PartialEq and Eq.

• resize and resize_default methods to Vec.

v0.2.0 - 2017-11-22

Added

• A single producer single consumer mode to RingBuffer.

• A truncate method to Vec.

Changed

• [breaking-change] Both Vec::new and RingBuffer::new no longer require an initial value. The signature of new is now const fn() -> Self.

• [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

• Initial release
