Struct OnceMap 

pub struct OnceMap<K, V> { /* private fields */ }

A map structure where each key can be set only once

This allows the get function to safely return unwrapped references to the values, while still allowing concurrent inserts.

Implementations

impl<K, V> OnceMap<K, V>

where K: Hash + Zeroable + Pod + PartialEq + Eq, V: Zeroable + Pod,

pub fn insert(&self, k: K, v: V) -> Result<()>

Insert a key-value pair into the map

pub fn get<O: Borrow<K>>(&self, o: &O) -> Option<&V>

Gets the value corresponding to the key, if any

Trait Implementations

impl<K, V> Substructure for OnceMap<K, V>

fn init(lf: GuardedLandfill) -> Result<Self>

Initialize a datastructure of this type, backed by landfill

fn flush(&self) -> Result<()>

Flush all data to disk
