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

This project adheres to Semantic Versioning.

Unreleased

0.4.10 - 2024-04-21

  • Respect RUSTC_WRAPPER in rustc version detection.

0.4.9 - 2022-01-03

  • Fix detection of -Z assume-incomplete-release in recent nightly compilers. (#39)

0.4.8 - 2021-05-19

  • Fix parsing of macro metavariable in attribute arguments. (#37)

0.4.7 - 2021-04-17

  • Support compiling with RUSTFLAGS='-Z assume-incomplete-release' on nightly compiler. (#35)

0.4.6 - 2021-03-27

  • Fix compatibility issues with const generics.

0.4.5 - 2021-01-05

  • Exclude unneeded files from crates.io.

0.4.4 - 2020-11-02

  • Accept const_fn attribute with no arguments and functions without const keyword. (#34) This allows const_fn to be used as an optional dependency.

    #[cfg_attr(feature = "...", const_fn::const_fn)]
pub fn func() {
    /* ... */
}

0.4.3 - 2020-11-02

  • const_fn no longer fails to compile if unable to determine rustc version. Instead, it now displays a warning. (#31)

  • const_fn no longer relies on debug print format. (#30)

0.4.2 - 2020-08-31

  • Improve error messages when failed to parse version information. (#26)

  • Fix compile failure with cargo installed by yum. (#26)

0.4.1 - 2020-08-25

  • Fix compile failure with non-cargo build systems. (#23)

0.4.0 - 2020-08-25

  • Add support for version-based code generation. (#17) The following conditions are available:

    use const_fn::const_fn;

// function is `const` on specified version and later compiler (including beta and nightly)
#[const_fn("1.36")]
pub const fn version() {
    /* ... */
}

// function is `const` on nightly compiler (including dev build)
#[const_fn(nightly)]
pub const fn nightly() {
    /* ... */
}

// function is `const` if `cfg(...)` is true
#[const_fn(cfg(...))]
pub const fn cfg() {
    /* ... */
}

// function is `const` if `cfg(feature = "...")` is true
#[const_fn(feature = "...")]
pub const fn feature() {
    /* ... */
}

  • Improve compile time by removing proc-macro related dependencies (#18, #20).

0.3.1 - 2019-12-09

  • Updated syn-mid to 0.5.

0.3.0 - 2019-10-20

  • #[const_fn] attribute may only be used on const functions.

0.2.1 - 2019-08-15

  • Updated proc-macro2, syn, and quote to 1.0.

  • Updated syn-mid to 0.4.

0.2.0 - 2019-06-16

0.1.7 - 2019-02-18

  • Update syn-mid version to 0.3
