Extra methods for str

Required Methods

fn rep(&self, n: usize) -> String

Repeat the string n times.

Requires feature="std"

fn append(&self, s: &str) -> String

Requires feature="std"

fn prefixes(&self) -> Prefixes

All non-empty prefixes

fn suffixes(&self) -> Suffixes

All non-empty suffixes

fn substrings(&self) -> Substrings

Produce all non-empty substrings

fn is_acceptable_index(&self, index: usize) -> bool

Return true if index is acceptable for slicing the string.

Acceptable indices are byte offsets from the start of the string that mark the start of an encoded utf-8 sequence, or an index equal to self.len().

Return false if the index is out of bounds.

For example the string "Abcαβγ" has length is 9 and the acceptable indices are 0, 1, 2, 3, 5, 7, and 9.

use odds::string::StrExt;
for &ix in &[0, 1, 2, 3, 5, 7, 9] {
    assert!("Abcαβγ".is_acceptable_index(ix));
}
