Struct tst::TSTSet
[−]
[src]
pub struct TSTSet { /* fields omitted */ }
A set based on a TSTMap
.
Methods
impl TSTSet
[src]
fn new() -> Self
[src]
fn len(&self) -> usize
[src]
Returns the number of elements in the set.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); assert_eq!(s.len(), 0); s.insert("xxx"); assert_eq!(s.len(), 1);
fn is_empty(&self) -> bool
[src]
Returns true if the set contains no elements.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); assert!(s.is_empty()); s.insert("yyyx"); assert!(!s.is_empty());
fn clear(&mut self)
[src]
Clears the set, removing all values.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); s.insert("abc"); s.insert("abd"); s.clear(); assert!(s.is_empty()); assert!(!s.contains("abc"));
fn contains(&self, key: &str) -> bool
[src]
Returns true
if the set contains a key
.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); s.insert("abc"); assert!(!s.contains("ab")); assert!(s.contains("abc"));
fn insert(&mut self, key: &str) -> bool
[src]
Adds a value to the set.
If the set did not have a value present, true
is returned.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); assert!(s.insert("abcd")); assert!(!s.insert("abcd")); assert_eq!(s.len(), 1);
fn remove(&mut self, key: &str) -> bool
[src]
Removes a value from the set. Returns true
if the value was
present in the set.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); s.insert("acde"); assert!(s.remove("acde")); assert!(!s.remove("acde"));
fn iter(&self) -> Iter
[src]
Gets an iterator over the TSTSet's contents.
Examples
use tst::TSTSet; let mut s: TSTSet = TSTSet::new(); s.insert("abc"); s.insert("bde"); s.insert("cfgx"); for x in s.iter() { println!("{}", x); }
fn wildcard_iter(&self, pat: &str) -> WildCardIter
[src]
An iterator returning all nodes matching wildcard pattern. Iterator element type is (String)
Examples
use tst::TSTSet; let mut s = TSTSet::new(); s.insert("a"); s.insert("b"); s.insert("c"); for x in s.wildcard_iter(".") { println!("{}", x); }
fn longest_prefix<'a>(&self, pref: &'a str) -> &'a str
[src]
Method returns longest prefix in the TSTSet.
Examples
use tst::TSTSet; let mut set = TSTSet::new(); set.insert("abc"); set.insert("abcd"); set.insert("abce"); set.insert("abca"); set.insert("zxd"); set.insert("add"); set.insert("abcdef"); assert_eq!("abcd", set.longest_prefix("abcde"));
fn prefix_iter(&self, pref: &str) -> Iter
[src]
Method returns iterator over all values with common prefix in the TSTSet.
Examples
use tst::TSTSet; let mut set = TSTSet::new(); set.insert("abc"); set.insert("abcd"); set.insert("abce"); set.insert("abca"); set.insert("zxd"); set.insert("add"); set.insert("abcdef"); for key in set.prefix_iter("abc") { println!("{}", key); } let first_key = set.iter().next().unwrap(); assert_eq!("abc".to_string(), first_key);

. Read more
impl PartialEq for TSTSet
[src]
fn eq(&self, __arg_0: &TSTSet) -> bool

and other
values to be equal, and is used by ==
. Read more

[src]
This method tests for !=
.
impl Eq for TSTSet
[src]
impl IntoIterator for TSTSet
[src]
type Item = String
The type of the elements being iterated over.
type IntoIter = IntoIter
Which kind of iterator are we turning this into?
fn into_iter(self) -> IntoIter
[src]
Creates a consuming iterator, that is, one that moves each key-value pair out of the TSTMap in arbitrary order. The TSTMap cannot be used after calling this.
Examples
use tst::TSTSet; let mut set = TSTSet::new(); set.insert("a"); set.insert("b"); set.insert("c"); let vec: Vec<String> = set.into_iter().collect();
