Enum Edition

Source 
pub enum Edition {
    Edition2015,
    Edition2018,
    Edition2021,
    Edition2024,
    EditionFuture,
}
Expand description

The edition of the compiler. (See RFC 2052.)

Variants§

§

Edition2015

The 2015 edition

§

Edition2018

The 2018 edition

§

Edition2021

The 2021 edition

§

Edition2024

The 2024 edition

§

EditionFuture

The future edition - this variant will always exist and features associated with this edition can be moved to the next 20XX edition when it is established and it is confirmed that those features will be part of that edition.

This variant allows edition changes to be implemented before being assigned to a concrete edition - primarily when there are two different unstable behaviours that need tested across an edition boundary.

This edition will be permanently unstable and any features associated with this edition must also be behind a feature gate.
