GrepPredicate

Struct GrepPredicate 

Source
pub struct GrepPredicate { /* private fields */ }
Expand description

AND-combined regex predicate applied to raw line bytes. Lines that fail UTF-8 decoding never match (mirrors what the interactive / search does).

Implementations§

Source§

impl GrepPredicate

Source

pub fn compile(patterns: &[String], case_mode: CaseMode) -> Result<Self, String>

Compile each pattern under the given case policy. Returns the first invalid pattern’s error, prefixed so the user can tell which --grep argument was bad. The case policy is applied via CaseMode::apply_to_pattern, so the (?i) flag is prepended when insensitivity is wanted.

Source

pub fn is_empty(&self) -> bool

Source

pub fn matches(&self, line: &[u8]) -> bool

True iff every compiled pattern matches the line. Empty predicate vacuously matches (callers should treat that as “no grep configured” via is_empty and not even ask).
