Struct Pattern 

pub struct Pattern { /* private fields */ }

One pattern’s table, checked once and kept.

static P: Pattern = Pattern::new(&[..]); with the bytes build returned.

Implementations

impl Pattern

pub const fn new(bytes: &'static [u8]) -> Self

pub fn load(&self) -> Result<(), Unusable>

Checks the table and keeps it, so a search never does. A caller checks each table once, before its first search.

pub fn is_match(&self, s: &str) -> Result<bool, Unusable>

Whether the pattern matches anywhere in s, as RE2’s MatchString does.

A corrupt table or a search the table can’t finish is an Err, never a panic. A table Pattern::load has not checked is checked now.
