search the needle

Required Methods

fn search<'a, P: SearchIn<'a>>(&'a self, needle: P) -> Option<usize>

search the needle in self.

return index of self, if it found the needle. Otherwise return None.

fn rsearch<'a, P: SearchIn<'a>>(&'a self, needle: P) -> Option<usize>

reverse search the needle in self.

return index of self, if it found the needle. Otherwise return None.

fn search_indices<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> SearchIndices<'a, P>

An iterator over the matches of needle in self.

Examples

use naive_opt::Search;

let v: Vec<_> = "abc345abc901abc".search_indices("abc").collect();
assert_eq!(v, [(0, "abc"), (6, "abc"), (12, "abc")]);

let v: Vec<_> = "0abcabc7".search_indices("abc").collect();
assert_eq!(v, [(1, "abc"), (4, "abc")]);

let v: Vec<_> = "ababa".search_indices("aba").collect();
assert_eq!(v, [(0, "aba")]); // only the first `aba`

fn rsearch_indices<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> RevSearchIndices<'a, P>

An reverse search iterator over the matches of needle in self.

Examples

use naive_opt::Search;

let v: Vec<_> = "abc345abc901abc".rsearch_indices("abc").collect();
assert_eq!(v, [(12, "abc"), (6, "abc"), (0, "abc")]);

let v: Vec<_> = "0abcabc7".rsearch_indices("abc").collect();
assert_eq!(v, [(4, "abc"), (1, "abc")]);

let v: Vec<_> = "ababa".rsearch_indices("aba").collect();
assert_eq!(v, [(2, "aba")]); // only the last `aba`

fn includes<'a, P: SearchIn<'a>>(&'a self, needle: P) -> bool

includes the needle in self.

returns true if the given pattern matches a sub-slice of this string slice. returns false if it does not.

fn search_ignore_ascii_case<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> Option<usize>

search the needle in self, ignore ascii case.

return index of self, if it found the needle. Otherwise return None.

fn rsearch_ignore_ascii_case<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> Option<usize>

reverse search the needle in self, ignore ascii case.

return index of self, if it found the needle. Otherwise return None.

fn search_indices_ignore_ascii_case<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> SearchIndicesIgnoreAsciiCase<'a, P>

An iterator over the matches of needle in self, ignore ascii case.

fn rsearch_indices_ignore_ascii_case<'a, P: SearchIn<'a>>( &'a self, needle: P, ) -> RevSearchIndicesIgnoreAsciiCase<'a, P>

An reverse search iterator over the matches of needle in self, ignore ascii case.

fn includes_ignore_ascii_case<'a, P: SearchIn<'a>>(&'a self, needle: P) -> bool

includes the needle in self, ignore ascii case.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
