Struct patterns::Pattern

pub struct Pattern { /* private fields */ }

A prepared pattern

Implementations

impl Pattern

pub fn new(pattern: &str) -> Self

Parse a pattern. Use the FromStr impl to return an error instead of panicking.

Panics

Panics if ParsePatternError is returned.

pub fn from_slice(bytes: &[u8], mask: u64) -> Self

Create a pattern from a byte slice and a mask. Byte slices longer than BYTES are cut short. Mask expects a u64 bitencoding. A 0 bit marks the byte as wildcard. Mask is trimmed to bytes.len().

Panics

Panics when all bytes are masked as wildcards.

pub fn matches<'pattern, 'data: 'cursor, 'cursor>( &'pattern self, data: &'data [u8] ) -> Scanner<'pattern, 'data, 'cursor>

Creates an iterator through data.

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Pattern

type Err = ParsePatternError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
