Enum GrepPatterns 

pub enum GrepPatterns {
    None,
    StrongOnly(Regex),
    WeakOnly(Regex),
    Both {
        strong: Regex,
        weak: Regex,
        highlight: Regex,
    },
}

Pattern configuration for grep, designed to make invalid states unrepresentable. The highlight regex is always derivable from the pattern state.

Variants

None

No grep patterns configured

StrongOnly(Regex)

Only strong (filtering) pattern

WeakOnly(Regex)

Only weak (highlighting) pattern

Both

Both strong and weak patterns, with precomputed combined highlight regex

Fields

strong: Regex

weak: Regex

highlight: Regex

Returns the strong (filtering) regex if configured.

pub fn weak(&self) -> Option<&Regex>

Returns the weak (highlight-only) regex if configured.

pub fn highlight(&self) -> Option<&Regex>

Returns true if a strong (filtering) pattern is configured.

pub fn is_active(&self) -> bool

Returns true if any pattern (strong or weak) is configured.
