Struct CompiledFuncname 

pub struct CompiledFuncname { /* private fields */ }

A compiled funcname spec: newline-separated POSIX regexes tried in order; a leading ! negates (a match rejects the line). Port of xdiff_set_find_func + ff_regexp from upstream xdiff-interface.c.

Implementations

impl CompiledFuncname

pub fn compile(spec: &[u8], extended: bool, icase: bool) -> Result<Self>

Compile a funcname spec. extended selects ERE (xfuncname / builtins) over BRE (funcname config). Errors mirror upstream’s die() calls byte-for-byte (printed to stderr, exit 128).

pub fn match_line(&self, line: &[u8]) -> Option<Vec<u8>>

Port of ff_regexp: match line (raw record bytes, trailing newline still attached) against the pattern list; return the heading bytes, or None when no pattern accepts the line.
