Enum Severity 

pub enum Severity {
    Off,
    Warn,
    Error,
    Fix,
}

Rule severity level. Configurable per rule in .marque.toml.

Ordering

The derived Ord is Off < Warn < Error < Fix. The ordering is exposed for consumers that want to compare severities (e.g., “is this at least Error?”) but the config loader does not use it as a merge operator today.

Merge semantics (current: last-write-wins)

marque-config merges layers in strict precedence order — env vars override .marque.local.toml which overrides .marque.toml. Whatever the highest-precedence layer says for a given rule wins, including downgrades: a local override of "off" will suppress a project-config "error". This is intentional — individual classifiers sometimes need to silence a rule while iterating, and the audit log still records the configured severity for every applied fix.

If a future policy requires strictness-only merging (where a lower layer cannot downgrade a higher layer’s severity), change the loader to .max() over Severity::parse_config values rather than extend. The derived Ord above is already the correct operator for that case.

Variants

Off

Rule is disabled entirely. FR-008: severity=off is unrepresentable on emitted diagnostics — a rule at Off never fires, so no Diagnostic is produced.

Warn

Emit warning; do not block.

Error

Emit error; blocks --check exit code.

Fix

Apply fix automatically when --fix flag is present.

Implementations

impl Severity

pub fn parse_config(s: &str) -> Option<Self>

Parse a severity level from a config string. Returns None for unrecognized values; the config loader treats None as a hard error.

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

Canonical lowercase string form, suitable for JSON output.

This is the inverse of Severity::parse_config and is the stable surface that JSON consumers should depend on — never format!("{:?}") (which exposes Debug formatting as an unintended API).

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

Formats the value using the given formatter.

impl Display for Severity

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

Formats the value using the given formatter.

impl Hash for Severity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Severity

fn cmp(&self, other: &Severity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Severity

fn partial_cmp(&self, other: &Severity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
