Enum MatchQuality 

pub enum MatchQuality {
    Prefix,
    WordStart,
    Substring,
    None,
}

How well a query matched an item’s name — better matches sort first.

Ordered by discriminant: Prefix is the strongest. Derived Ord gives the comparison for free, so adding a tier in the right position is all it takes.

Variants

Prefix

The name starts with the query — “parks” in “Parks and Recreation”.

WordStart

Some later word starts with the query — “recreation” in “Parks and Recreation”. Still a deliberate hit: users type whole words.

Substring

The query appears mid-word — “parks” in “Sparks of Love”. Weakest hit that still counts as a match.

None

No match on the name at all. The backend returned it for some other reason (overview, artist, album), so it is kept but sorted last.

Trait Implementations

impl Clone for MatchQuality

fn clone(&self) -> MatchQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatchQuality

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

Formats the value using the given formatter.

impl Ord for MatchQuality

fn cmp(&self, other: &MatchQuality) -> 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 MatchQuality

fn eq(&self, other: &MatchQuality) -> 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 MatchQuality

fn partial_cmp(&self, other: &MatchQuality) -> 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.
