atoi

🚀 Features

• Add support for isize and usize on 32 and 64 bit platforms

🚀 Features

• Add support for isize and usize on 32 and 64 bit platforms

🚀 Features

• [breaking] Minimal supported rust compiler now 1.86.0

• [breaking] Remove ascii_to_digit

• [breaking] Remove trait MaxNumDigits

• [breaking] Remove enumeration Sign

  It is now an implementation detail of integer

🚜 Refactor

• [breaking] FromRadix10 and its sibling traits used to be implement for any type with a neutral element of addition Zero, its successor One, AddAssign and MulAssign. This allowed it to work not only for builtin types like i32, but also for big integer implementations from other crates. However, it made it also hard to optimize for builtin types. FromRadix10 and its sibling traits FromRadix10Signed, FromRadixSignedChecked, FromRadix16 are now explicitly implemented for builtin types. The generic implementation can still be used by wrapping the type in the new Integer wrapper.

⚡ Performance

• Inline from_radix_* functions for builtin types

  Since these are no longer generic, we do not get the inlining for free.
  Benchmarks show significant regressions otherwise

• Speed up hexdigit parsing by using masks to unify ascii cases

  Thanks to okaneco for the idea

⚙️ Miscellaneous Tasks

• [breaking] Minimal toolchain is now 1.86.0
• [breaking] Remove Sign from public interface

automatically test no-std on CI

• Minimal supported compiler is Rust 1.57.0
• Support for no-std by making std a default feature which can be opted out of.

• Minimal supported compiler is Rust 1.56.0
• Changed Rust edition to 2021
• Stabilized interface

• The atoi function now supports parsing signed integers. Use the FromRadix10 trait directly if you wish to not allow leading + or - signs.

• Introduce FromRadix10Signed and FromRadix10SignedChecked for parsing signed integers.

• Add support for hex numbers through FromRadix16 and FromRadix16Checked.
• Fix: Documentation of FromRadix10Checked now has code samples using this trait.

fix documentation of overflow behaviour

• Fix: Fixed documentation of atois overflow behaviour.

• Added From_radix_10_checked.
• Breaking change: atoi now returns None on overflow

• Documentation now hints at FromRadix10 trait.
• Updated to Rust 2018
