Struct Match 

pub struct Match<'a> {
    pub haystack: &'a str,
    pub start: usize,
    pub end: usize,
}

Returned by Pattern on match.

Fields

haystack: &'a str

The string that was searched in

start: usize

Start of the match

end: usize

End of the match

Implementations

impl<'a> Match<'a>

pub fn new(haystack: &'a str, start: usize, end: usize) -> Self

Create a match from a haystack &str and start..end range.

Panics

When start >= end or haystack.len() < end.

Example

let mat = Match::new("don't go to far...", 0, 100000);

pub fn len(&self) -> usize

Returns the number of char in the match

Example

assert_eq!(Match::new("three", 1, 4).len(), 3);

pub fn as_str(&self) -> &'a str

Convert to to &str.

Example

let mat = Match::new("it's here not here", 5, 9);

assert_eq!(mat.as_str(), "here");

Trait Implementations

impl<'a> Clone for Match<'a>

fn clone(&self) -> Match<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Match<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Match<'a>

fn eq(&self, other: &Match<'a>) -> 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<'a> ToString for Match<'a>

fn to_string(&self) -> String

Converts the given value to a String.
