Enum Fuzziness 

pub enum Fuzziness {
    Edits(u8),
    Detailed(FuzzyLimits),
    MrabStyle(MrabFuzziness),
    Inherited,
    Exact,
}

Fuzziness specification for a literal segment.

Supports two syntax styles:

1. Simple: hello~2 (allows 2 total edits)
2. mrab-style: (?:hello){i<=1,d<=2} (max 1 insertion, 2 deletions)

Variants

Edits(u8)

Simple edit count: hello~2 allows 2 total edits.

Detailed(FuzzyLimits)

Detailed limits: hello~{i=1,d=0,s=2} or mrab-style {i<=1,d<=2}.

MrabStyle(MrabFuzziness)

mrab-style specification with optional cost constraints. {i<=1,s<=2,2i+2d+1s<=4}

Inherited

Inherit from global/parent settings.

Exact

Exact match only (no fuzzy matching): hello~0.

Implementations

impl Fuzziness

pub fn to_limits(&self, default_edits: u8) -> Option<FuzzyLimits>

Convert to FuzzyLimits, using default if inherited.

pub fn min_edits(&self) -> Option<u8>

Get the minimum edits required (for exclusive lower bounds like {0<e<5}).

Trait Implementations

impl Clone for Fuzziness

fn clone(&self) -> Fuzziness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fuzziness

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

Formats the value using the given formatter.

impl Default for Fuzziness

fn default() -> Fuzziness

Returns the “default value” for a type.

impl PartialEq for Fuzziness

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