Expand description

The reason for future incompatibility

Variants

`FutureReleaseError`

This will be an error in a future release for all editions

`FutureReleaseErrorReportNow`

This will be an error in a future release, and Cargo should create a report even for dependencies

`FutureReleaseSemanticsChange`

Code that changes meaning in some way in a future release.

`EditionError(Edition)`

Previously accepted code that will become an error in the provided edition

`EditionSemanticsChange(Edition)`

Code that changes meaning in some way in the provided edition

`Custom(&'static str)`

A custom reason.
