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

[−]

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

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

[−]

An 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)
