Enum Severity 

#[non_exhaustive]
pub enum Severity {
    Error,
    Warning,
    Note,
}

Severity of a Diagnostic.

Hosts route diagnostics by severity: Error blocks downstream rendering or fails CI, Warning decorates the editor surface, Note is informational. The aozora library never panics on a Diagnostic — the parser produces a best-effort output and surfaces this enum as the host’s policy hook.

Variants (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

Genuine error; downstream consumers should treat the parse as suspect.

Warning

Recoverable observation; parse continues and output is preserved, but the user should know.

Note

Informational note; editor surfaces may show it as a tooltip or annotation but it does not affect CI / build status.

Implementations

impl Severity

pub const ALL: [Severity; 3]

Every variant in declaration order. Used by codegen so downstream artefacts track the enum without drift.

pub const fn as_wire_str(self) -> &'static str

Stable lowercase wire-format identifier (“error” / “warning” / “note”). The same string the driver wire format emits in the severity field of DiagnosticWire.

Trait Implementations

impl Clone for Severity

fn clone(&self) -> Severity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Severity

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Severity

fn eq(&self, other: &Severity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
