Enum ValidationSeverity 

#[non_exhaustive]
pub enum ValidationSeverity {
    Critical,
    Error,
    Warning,
    Info,
}

Priority level for a validation error or warning.

Marked #[non_exhaustive] so that adding new severity levels in future releases is not a breaking change for downstream match arms.

Ordering

Comparison follows severity, not declaration order: Info < Warning < Error < Critical. The derived ordering said the opposite — it ranked Critical lowest, so issues.max_by_key(|i| i.severity) picked the least important issue — while numeric_level said the reverse. One of the two had to give, and the one that matches the word “severity” wins.

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.

Critical

Structural parse failure; processing cannot continue.

Error

Structural validation failed; message is invalid.

Warning

Data validation warning (e.g., code-list mismatch); message may be usable.

Info

Informational note; message is valid but noteworthy.

Implementations

impl ValidationSeverity

pub fn as_str(self) -> &'static str

Return a lowercase ASCII string for this severity level.

Stable for the four known variants. Because the enum is #[non_exhaustive], new variants added in future releases are handled by a catch-all arm that returns "unknown" so that existing code keeps compiling and serialising gracefully.

pub fn numeric_level(self) -> u8

Return a numeric priority for this severity level.

Higher values indicate higher severity: Critical = 3, Error = 2, Warning = 1, Info = 0. This is also the basis of the Ord impl.

Because the enum is #[non_exhaustive], a variant added in a future release that this build does not know about ranks below Info.
