Changelog

This project follows semantic versioning.

The MSRV (Minimum Supported Rust Version) is 1.37.0, and typenum is tested against this Rust version.

Unreleased

  • [removed] Remove force_unix_path_separator feature, make it the default
  • [added] docs.rs metadata and cfg options
  • [added] Playground metadata

1.16.0 (2022-12-05)

  • [added] const INT field to the ToInt trait.
  • [added] const-generics field with U<N> mapping where N is a const generic.

1.15.0 (2021-12-25)

  • [fixed] Cross-compilation issue due to doing math in build script. (PR #177)
  • [added] New feature scale_info for using inside Substrate-based runtimes (PR #175)

1.14.0 (2021-09-01)

  • [changed] Sealed all marker traits. Documentation already stated that these should not be implemented outside the crate, so this is not considered a breaking change.

1.13.0 (2021-03-12)

  • [changed] MSRV from 1.22.0 to 1.37.0.
  • [fixed] op macro with 2018 edition import.
  • [changed] Allowed calling assert_type_eq and assert_type at top level.
  • [added] Marker trait Zero for Z0, U0, and B0.
  • [added] Implementation of Pow trait for f32 and f64 with negative exponent.
  • [added] Trait ToInt.

1.12.0 (2020-04-13)

  • [added] Feature force_unix_path_separator to support building without Cargo.
  • [added] Greatest common divisor operator Gcd with alias Gcf.
  • [added] gcd to the op! macro.
  • [changed] Added Copy bound to Rhs of Mul<Rhs> impl for <TArr<V, A>.
  • [changed] Added Copy bound to Rhs of Div<Rhs> impl for <TArr<V, A>.
  • [changed] Added Copy bound to Rhs of PartialDiv<Rhs> impl for <TArr<V, A>.
  • [changed] Added Copy bound to Rhs of Rem<Rhs> impl for <TArr<V, A>.
  • [fixed] Make all functions #[inline].

1.11.2 (2019-08-26)

  • [fixed] Cross compilation from Linux to Windows.

1.11.1 (2019-08-25)

  • [fixed] Builds on earlier Rust builds again and added Rust 1.22.0 to Travis to prevent future breakage.

1.11.0 (2019-08-25)

  • [added] Integer log2 to the op! macro.
  • [added] Integer binary logarithm operator Logarithm2 with alias Log2.
  • [changed] Removed feature(i128_type) when running with the i128 feature. Kept the feature flag. for typenum to maintain compatibility with old Rust versions.
  • [added] Integer sqrt to the op! macro.
  • [added] Integer square root operator SquareRoot with alias Sqrt.
  • [fixed] Bug with attempting to create U1024 type alias twice.

1.10.0 (2018-03-11)

  • [added] The PowerOfTwo marker trait.
  • [added] Associated constants for Bit, Unsigned, and Integer.

1.9.0 (2017-05-14)

  • [added] The Abs type operator and corresponding AbsVal alias.
  • [added] The feature i128 that enables creating 128-bit integers from typenums.
  • [added] The assert_type! and assert_type_eq! macros.
  • [added] Operators to the op! macro, including those performed by cmp!.
  • [fixed] Bug in op! macro involving functions and convoluted expressions.
  • [deprecated] The cmp! macro.

1.8.0 (2017-04-12)

  • [added] The op! macro for conveniently performing type-level operations.
  • [added] The cmp! macro for conveniently performing type-level comparisons.
  • [added] Some comparison type-operators that are used by the cmp! macro.

1.7.0 (2017-03-24)

  • [added] Type operators Min and Max with accompanying aliases Minimum and Maximum

1.6.0 (2017-02-24)

  • [fixed] Bug in Array division.
  • [fixed] Bug where Rem would sometimes exit early with the wrong answer.
  • [added] PartialDiv operator that performs division as a partial function -- it's defined only when there is no remainder.

1.5.2 (2017-02-04)

  • [fixed] Bug between Div implementation and type system.

1.5.1 (2016-11-08)

  • [fixed] Expanded implementation of Pow for primitives.

1.5.0 (2016-11-03)

  • [added] Functions to the Pow and Len traits. This is technically a breaking change, but it would only break someone's code if they have a custom impl for Pow. I would be very surprised if that is anyone other than me.

1.4.0 (2016-10-29)

  • [added] Type-level arrays of type-level integers. (PR #66)
  • [added] The types in this crate are now instantiable. (Issue #67, PR #68)

  • [fixed] Bug with recent nightlies.

1.3.0 (2016-02-07)

  • [changed] Removed dependency on libstd. (Issue #53, PR #55)
  • [changed] Reorganized module structure. (PR #57)

1.2.0 (2016-01-03)

  • [added] This change log!
  • [added] Convenience type aliases for operators. (Issue #48, PR #50)
  • [added] Types in this crate now derive all possible traits. (Issue #42, PR #51)
