Implementations

impl Pattern

pub fn parse(input: &str) -> Result<Pattern, Error>

Parse a pattern expression from a string.

pub fn parse_partial(input: &str) -> Result<(Pattern, usize), Error>

Parses a pattern from the beginning of a string and returns both the parsed Pattern and the number of bytes consumed.

Unlike parse(), this function succeeds even if additional characters follow the first pattern. The returned index points to the first unparsed character after the pattern.

Example

let (pattern, consumed) = Pattern::parse_partial("true rest").unwrap();
assert_eq!(pattern, Pattern::bool(true));
assert_eq!(consumed, 5); // "true ".len() - includes whitespace

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Display for Pattern

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

Formats the value using the given formatter.

impl PartialEq for Pattern

fn eq(&self, other: &Pattern) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for Pattern

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Pattern, Error>

Performs the conversion.
