The reason for future incompatibility

Variants

FutureReleaseErrorDontReportInDeps

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

This will not show up in cargo’s future breakage report. The warning will hence only be seen in local crates, not in dependencies.

FutureReleaseErrorReportInDeps

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

This is the only reason that will make future incompatibility warnings show up in cargo’s reports. All other future incompatibility warnings are not visible when they occur in a dependency.

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.
