Struct aho_corasick::util::prefilter::RareByteOffsets

struct RareByteOffsets {
    set: [RareByteOffset; 256],
}

A set of byte offsets, keyed by byte.

Fields

set: [RareByteOffset; 256]

Each entry corresponds to the maximum offset of the corresponding byte across all patterns seen.

Implementations

impl RareByteOffsets

pub(crate) fn empty() -> RareByteOffsets

Create a new empty set of rare byte offsets.

pub(crate) fn set(&mut self, byte: u8, off: RareByteOffset)

Add the given offset for the given byte to this set. If the offset is greater than the existing offset, then it overwrites the previous value and returns false. If there is no previous value set, then this sets it and returns true.

Trait Implementations

impl Clone for RareByteOffsets

fn clone(&self) -> RareByteOffsets
