Enum OptimizationHint 

pub enum OptimizationHint {
    Optimal,
    UseIdSelector {
        current: String,
        suggested: String,
    },
    TooBroad {
        reason: String,
    },
    PreferChildCombinator {
        at: String,
    },
    AvoidUniversalSelector,
    CacheSelector,
}

Performance hint for selector optimization.

Variants

Optimal

Selector is already optimal.

UseIdSelector

Consider using ID selector for better performance.

Fields

current: String

Current selector pattern.

suggested: String

Suggested optimized selector.

TooBroad

Selector is too broad, consider being more specific.

Fields

reason: String

Reason why the selector is too broad.

PreferChildCombinator

Descendant combinator can be slow, consider child combinator.

Fields

at: String

Location of the descendant combinator.

AvoidUniversalSelector

Universal selector (*) should be avoided.

CacheSelector

Consider caching this compiled selector.

Trait Implementations

impl Clone for OptimizationHint

fn clone(&self) -> OptimizationHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizationHint

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

Formats the value using the given formatter.

impl PartialEq for OptimizationHint

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