Enum WarningKind 

#[non_exhaustive]
pub enum WarningKind {
    LossyDrop,
    Approximated,
    Unsupported,
}

Class of information loss in a ConversionWarning.

New variants are appended; existing variants are stable across minor versions. Marked #[non_exhaustive] so adding a variant is non-breaking for downstream match arms.

Copy is intentional here because every variant is fieldless, matching the per-warning struct (ConversionWarning) which owns the attached message and is therefore not Copy.

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.

LossyDrop

A feature in the source format has no equivalent in the target format and was dropped (e.g. lyrics on a ChordPro→iReal conversion — iReal has no lyrics surface).

Approximated

A feature in the source format was approximated to the nearest equivalent in the target format (e.g. an unusual section label mapped to the closest iReal letter).

Unsupported

A feature in the source format is not yet supported by the converter, even though the target format could in principle represent it. Distinct from LossyDrop because resolving it is a future converter-side change rather than an inherent format limitation.

Trait Implementations

impl Clone for WarningKind

fn clone(&self) -> WarningKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WarningKind

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

Formats the value using the given formatter.

impl PartialEq for WarningKind

fn eq(&self, other: &WarningKind) -> 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.
