v1.2.0

Compatibility Notes

This version of strftime-ruby bumps the MSRV to Rust 1.84.0.

rustc 1.87.0 will introduce changes to format machinery which cause panics in older versions of strftime-ruby for formatting strings which specify padding amounts larger than u16::MAX. v1.2.0 addresses these issues.

Full Changelog: v1.0.0...v1.0.1

v1.0.0

Release 1.0.0 of strftime-ruby.

strftime-ruby is available on crates.io.

strftime-ruby is a Ruby 3.1.2 compatible implementation of the Time#strftime method. The strftime routines provided by this crate are POSIX-compatible, except for intentionally ignoring the E and O modified conversion specifiers.

API

There are 5 strftime functions in this crate which vary in the type of format specifier they take and how they write the formatted output:

• strftime::buffered::strftime: Takes a &[u8] format specifier and writes to the provided byte slice.
• strftime::fmt::strftime: Takes a &str format specifier and writes to the provided core::fmt::Write object.
• strftime::bytes::strftime: Takes a &[u8] format specifier and writes to a newly allocated Vec, which is returned.
• strftime::string::strftime: Takes a &str format specifier and writes to a newly allocated String, which is returned.
• strftime::io::strftime: Takes a &[u8] format specifier and writes to the provided std::io::Write object.

Allocations

The only routines that allocate in this crate are strftime::bytes::strftime and strftime::string::strftime. These routines use fallible allocation APIs from alloc and return errors to callers.

strftime::fmt::strftime and strftime::io::strftime perform no allocations on their own, but the provided writers may allocate.

Cargo Features

strftime-ruby has alloc and std features. All features are enabled by default.

strftime::buffered::strftime and strftime::fmt::strftime are available when this crate is compiled without any features and are usable in a no_std context.

The alloc feature enables strftime::bytes::strftime and strftime::string::strftime.

The std feature enables strftime::io::strftime.

Test Coverage

strftime-ruby has 100% line coverage, which is enforced by CI, and is fuzzed regularly.

Composition

strftime-ruby's APIs take an implementation of its Time trait to determine the values used with format specifiers. The intent is that time crates across the ecosystem can implement it, making this crate fully interoperable across all time implementations.
