[−][src]Struct swipc_gen::gen_rust_code::BUILTINS
SwIPC builtin type. Associates a SwIPC builtin name with a size/alignment and a rust type name.
Fields
__private_field: ()
Methods from Deref<Target = HashMap<&'static str, (u8, &'static str)>>
pub fn capacity(&self) -> usize
1.0.0[src]
Returns the number of elements the map can hold without reallocating.
This number is a lower bound; the HashMap<K, V>
might be able to hold
more, but is guaranteed to be able to hold at least this many.
Examples
use std::collections::HashMap; let map: HashMap<i32, i32> = HashMap::with_capacity(100); assert!(map.capacity() >= 100);
pub fn keys(&self) -> Keys<K, V>
1.0.0[src]
An iterator visiting all keys in arbitrary order.
The iterator element type is &'a K
.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert("a", 1); map.insert("b", 2); map.insert("c", 3); for key in map.keys() { println!("{}", key); }
pub fn values(&self) -> Values<K, V>
1.0.0[src]
An iterator visiting all values in arbitrary order.
The iterator element type is &'a V
.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert("a", 1); map.insert("b", 2); map.insert("c", 3); for val in map.values() { println!("{}", val); }
pub fn iter(&self) -> Iter<K, V>
1.0.0[src]
An iterator visiting all key-value pairs in arbitrary order.
The iterator element type is (&'a K, &'a V)
.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert("a", 1); map.insert("b", 2); map.insert("c", 3); for (key, val) in map.iter() { println!("key: {} val: {}", key, val); }
pub fn len(&self) -> usize
1.0.0[src]
Returns the number of elements in the map.
Examples
use std::collections::HashMap; let mut a = HashMap::new(); assert_eq!(a.len(), 0); a.insert(1, "a"); assert_eq!(a.len(), 1);
pub fn is_empty(&self) -> bool
1.0.0[src]
Returns true
if the map contains no elements.
Examples
use std::collections::HashMap; let mut a = HashMap::new(); assert!(a.is_empty()); a.insert(1, "a"); assert!(!a.is_empty());
pub fn hasher(&self) -> &S
1.9.0[src]
Returns a reference to the map's BuildHasher
.
Examples
use std::collections::HashMap; use std::collections::hash_map::RandomState; let hasher = RandomState::new(); let map: HashMap<i32, i32> = HashMap::with_hasher(hasher); let hasher: &RandomState = map.hasher();
pub fn get<Q>(&self, k: &Q) -> Option<&V> where
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
1.0.0[src]
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
Returns a reference to the value corresponding to the key.
The key may be any borrowed form of the map's key type, but
Hash
and Eq
on the borrowed form must match those for
the key type.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert(1, "a"); assert_eq!(map.get(&1), Some(&"a")); assert_eq!(map.get(&2), None);
pub fn get_key_value<Q>(&self, k: &Q) -> Option<(&K, &V)> where
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
1.40.0[src]
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
Returns the key-value pair corresponding to the supplied key.
The supplied key may be any borrowed form of the map's key type, but
Hash
and Eq
on the borrowed form must match those for
the key type.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert(1, "a"); assert_eq!(map.get_key_value(&1), Some((&1, &"a"))); assert_eq!(map.get_key_value(&2), None);
pub fn contains_key<Q>(&self, k: &Q) -> bool where
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
1.0.0[src]
K: Borrow<Q>,
Q: Hash + Eq + ?Sized,
Returns true
if the map contains a value for the specified key.
The key may be any borrowed form of the map's key type, but
Hash
and Eq
on the borrowed form must match those for
the key type.
Examples
use std::collections::HashMap; let mut map = HashMap::new(); map.insert(1, "a"); assert_eq!(map.contains_key(&1), true); assert_eq!(map.contains_key(&2), false);
pub fn raw_entry(&self) -> RawEntryBuilder<K, V, S>
[src]
hash_raw_entry
)Creates a raw immutable entry builder for the HashMap.
Raw entries provide the lowest level of control for searching and manipulating a map. They must be manually initialized with a hash and then manually searched.
This is useful for
- Hash memoization
- Using a search key that doesn't work with the Borrow trait
- Using custom comparison logic without newtype wrappers
Unless you are in such a situation, higher-level and more foolproof APIs like
get
should be preferred.
Immutable raw entries have very limited use; you might instead want raw_entry_mut
.
