Enum nucleo_matcher::pattern::AtomKind

#[non_exhaustive]
pub enum AtomKind {
    Fuzzy,
    Substring,
    Prefix,
    Postfix,
    Exact,
}

The kind of matching algorithm to run for an atom.

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.

Fuzzy

Fuzzy matching where the needle must match any haystack characters (match can contain gaps). This atom kind is used by default if no special syntax is used. There is no negated fuzzy matching (too many false positives).

See also Matcher::fuzzy_match.

Substring

The needle must match a contiguous sequence of haystack characters without gaps. This atom kind is parsed from the following syntax: 'foo and !foo (negated).

See also Matcher::substring_match.

Prefix

The needle must match all leading haystack characters without gaps or prefix. This atom kind is parsed from the following syntax: ^foo and !^foo (negated).

See also Matcher::prefix_match.

Postfix

The needle must match all trailing haystack characters without gaps or postfix. This atom kind is parsed from the following syntax: foo$ and !foo$ (negated).

See also Matcher::postfix_match.

Exact

The needle must match all haystack characters without gaps or prefix. This atom kind is parsed from the following syntax: ^foo$ and !^foo$ (negated).

See also Matcher::exact_match.

Trait Implementations

impl Clone for AtomKind

fn clone(&self) -> AtomKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AtomKind

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

Formats the value using the given formatter.

impl PartialEq for AtomKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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