Struct bones_framework::asset::prelude::dashmap::DashMap

pub struct DashMap<K, V, S = RandomState> { /* private fields */ }
Expand description

DashMap is an implementation of a concurrent associative array/hashmap in Rust.

DashMap tries to implement an easy to use API similar to std::collections::HashMap with some slight changes to handle concurrency.

DashMap tries to be very simple to use and to be a direct replacement for RwLock<HashMap<K, V, S>>. To accomplish this, all methods take &self instead of modifying methods taking &mut self. This allows you to put a DashMap in an Arc<T> and share it between threads while being able to modify it.

Documentation mentioning locking behaviour acts in the reference frame of the calling thread. This means that it is safe to ignore it across multiple threads.

Implementations§

§

impl<'a, K, V> DashMap<K, V>
where K: 'a + Eq + Hash, V: 'a,

pub fn new() -> DashMap<K, V>

Creates a new DashMap with a capacity of 0.

§Examples
use dashmap::DashMap;

let reviews = DashMap::new();
reviews.insert("Veloren", "What a fantastic game!");

pub fn with_capacity(capacity: usize) -> DashMap<K, V>

Creates a new DashMap with a specified starting capacity.

§Examples
use dashmap::DashMap;

let mappings = DashMap::with_capacity(2);
mappings.insert(2, 4);
mappings.insert(8, 16);

pub fn with_shard_amount(shard_amount: usize) -> DashMap<K, V>

Creates a new DashMap with a specified shard amount

shard_amount should greater than 0 and be a power of two. If a shard_amount which is not a power of two is provided, the function will panic.

§Examples
use dashmap::DashMap;

let mappings = DashMap::with_shard_amount(32);
mappings.insert(2, 4);
mappings.insert(8, 16);

pub fn with_capacity_and_shard_amount( capacity: usize, shard_amount: usize, ) -> DashMap<K, V>

Creates a new DashMap with a specified capacity and shard amount.

shard_amount should greater than 0 and be a power of two. If a shard_amount which is not a power of two is provided, the function will panic.

§Examples
use dashmap::DashMap;

let mappings = DashMap::with_capacity_and_shard_amount(32, 32);
mappings.insert(2, 4);
