[−][src]Trait substring::Substring
Provides a substring() method.
The substring() method obtains a string slice of characters within the range specified by
start_index and end_index.
Required methods
fn substring(&self, start_index: usize, end_index: usize) -> &str
Obtains a string slice containing the characters within the range specified by
start_index and end_index.
The range specified is a character range, not a byte range.
Implementors
impl Substring for str[src]
Implements a substring() method for str.
Note that structs which implement Deref<Target=str> (such as String) will also have
access to this implementation.
fn substring(&self, start_index: usize, end_index: usize) -> &str[src]
Obtain a slice of the characters within the range of start_index and end_index.
As this is by character index, rather than byte index, the temporal complexity of finding a substring is O(n), where n is the byte length of the string.
Example:
use substring::Substring; assert_eq!("foobar".substring(2,5), "oba");
