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 - ReleaseDate

Changed

  • Bumped MSRV to 1.71.0
  • Updated hashbrown to 0.14.0
  • Updated dashmap to 0.6.0

0.7.2 - 2023-05-15

0.7.1 - 2023-05-15

0.7.0 - 2023-04-02

Changed

  • Bumped MSRV to 1.61.0
  • Updated to 2021 edition
  • Interning empty strings no longer counts towards the memory limit of any interners. Empty strings now take up zero bytes and therefore will neither allocate nor cause methods to return errors or throw panics if the interner is out of memory.
  • Changed ThreadedRodeo to use a new lockfree interner that no longer requires taking a mutex in order to allocate within it
  • Updated DashMap and Hashbrown dependencies

Added

  • Added blanket implementations of Reader and Resolver for &T and &mut T references to types that implement those traits, and Interner likewise for &mut T
  • Added Clone implementation for Rodeo
  • Added the Rodeo::try_clone() and Rodeo::try_clone_from() functions

0.6.0 - 2021-09-01

Changed

  • Changed the Debug implementations of all key types to be more condensed

Added

  • Added an .into_inner() method to each key type that exposes the backing NonZeroU* it's made of

0.5.1 - 2021-06-01

Fixed

  • Fixed compile error in release mode when using the serialize feature

0.5.0 - 2021-02-19

Added

  • Implemented Interner, Reader and Resolver for &ThreadedRodeo
  • Added optional implementations of Abomonation for key types under the abomonation feature flag
  • Added optional implementations of DeepSizeOf for key types under the deepsize feature flag
  • Added iterators for ThreadedRodeo

Changed

  • Moved the .into_reader() and .into_resolver() traits from Interner and Reader into the new IntoReader, IntoResolver and IntoReaderAndResolver traits
  • Updated dependencies

Fixed

  • Fixed race condition on key insertion for ThreadedRodeo

0.4.1 - 2021-01-03

Changed

  • Updated dependencies to latest versions
  • Made Interner, Reader and Resolver default their generic arguments to Spur

0.4.0 - 2021-01-02

Added

  • Added the MemoryLimits struct for creating memory limits on interners
  • Gave Rodeo & ThreadedRodeo the ability to be given a hard memory capacity, currently only limiting the amount of memory allocated within the arena it uses
  • Added the with_memory_limits, with_capacity_and_memory_limits and with_capacity_memory_limits_and_hasher methods to Rodeo & ThreadedRodeo for creating interners with memory limits
  • Added set_memory_limits to Rodeo & ThreadedRodeo for in-flight modification of memory limits
  • Added current_memory_usage and max_memory_usage methods to Rodeo & ThreadedRodeo for introspection of current memory usage maximum memory usage
  • Added FromIterator, Extend and IntoIterator implementations for Rodeo
  • Added ExactSizeIterator implementations for Iter and Strings
  • Added IntoIterator implementations for RodeoReader and RodeoResolver
  • Added the inline-more feature to enable inlining (off by default)
  • Added FromIterator and Extend implementations to ThreadedRodeo
  • Added the .contains() and the .contains_key() methods to Rodeo, ThreadedRodeo, RodeoReader and RodeoResolver
  • Implemented Serialize and Deserialize for Rodeo, ThreadedRodeo, RodeoReader and RodeoResolver
  • Added Eq and PartialEq implementations through the various interners
  • Added Index implementations for all interners
  • Added the Interner, Reader and Resolver traits
  • Loosened trait bounds on Rodeo methods

Changed

  • Debug views of all interners now show their arenas
  • Made Key::into_usize safe
  • External apis are no longer #[inline] by default, for that use the inline-more feature
  • .get_or_intern() and .get_or_intern_static() now return a Result<T, LassoError> to allow intelligently handling failure
  • Bumped MSRV to 1.40.0
  • Removed dependency on serde derive

0.3.1 - 2020-07-24

Added

  • Added the get_or_intern_static and try_get_or_intern_static methods to ThreadedRodeo (Thanks to @jonas-schievink)

Fixed

0.3.0 - 2020-07-12

This version really wouldn't be possible without the amazing work of @CAD97. They were an amazing asset in improving the memory efficiency of lasso and I can't thank them enough

Added

  • Added the get_or_intern_static and try_get_or_intern_static methods for zero-copy static string internment
  • Added the Capacity struct for better internment estimates and more accurate pre-allocation

Changed

  • Lasso's single-threaded configuration now supports back to Rust 1.34! Thanks to @jyn514 for their hard work!
  • Rodeo and RodeoReader now use less memory since they only store their interned strings' pointers once
  • Rodeo and RodeoReader use a different hashing strategy for their maps, instead of using a hashed string and key pair, they now use the key hashed as their paired string. This allows for decreased memory usage
  • The arena backing all interners now increases the amount of memory it allocates exponentially (The same doubling strategy used by Vec is used). This allows for fewer allocations to happen as more strings are interned
  • hashbrown is now a default dependency due to HashMap's raw_api not being stable
  • Relaxed trait bounds of many structs and functions
  • Made custom Debug implementations to cut the excess and unneeded output
  • Exported the Strings and Iter structs
  • The with_capacity methods now use the Capacity struct

Removed

  • Removed the hashbrown-table and nightly features

0.2.4

Added

  • Added Serde support with the serialize feature

0.2.2

Fixed

  • Fixed Send for Rodeo

  • Added lifetimes to all Rodeo types
  • Added lifetime to Key
  • Added the ID requirement to Key
  • Added try_resolves and resolve_uncheckeds
