Expand description

An enum representing a diagnostic level.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Error

Warning
🔬 This is a nightly-only experimental API. (proc_macro_diagnostic #54140)

A warning.

Note
🔬 This is a nightly-only experimental API. (proc_macro_diagnostic #54140)

A note.

Help
🔬 This is a nightly-only experimental API. (proc_macro_diagnostic #54140)
