Expand description
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.
