Expand description

Indicates the confidence in the correctness of a suggestion.

All suggestions are marked with an Applicability. Tools use the applicability of a suggestion to determine whether it should be automatically applied or if the user should be consulted before applying the suggestion.

Variants

MachineApplicable

The suggestion is definitely what the user intended, or maintains the exact meaning of the code. This suggestion should be automatically applied.

In case of multiple MachineApplicable suggestions (whether as part of the same multipart_suggestion or not), all of them should be automatically applied.

MaybeIncorrect

The suggestion may be what the user intended, but it is uncertain. The suggestion should result in valid Rust code if it is applied.

HasPlaceholders

The suggestion contains placeholders like (...) or { /* fields */ }. The suggestion cannot be applied automatically because it will not result in valid Rust code. The user will need to fill in the placeholders.

Unspecified

The applicability of the suggestion is unknown.
