Struct prost_sled::ProtoTree

pub struct ProtoTree(_);

Wrapper around sled::Tree that allows you to use types implementing prost::Message instead of raw bytes.

Implementations

impl ProtoTree

pub fn contains_key<K>(&self, key: K) -> Result<bool> where
    K: AsRef<[u8]>, 

pub fn get<K, T>(&self, key: K) -> Result<Option<T>> where
    K: AsRef<[u8]>,
    T: Message + Default, 

Get a value by its key.

pub fn update_and_fetch<K, V, F, T>(&self, key: K, f: F) -> Result<Option<T>> where
    K: AsRef<[u8]>,
    F: FnMut(Option<T>) -> Option<V>,
    V: Into<T>,
    T: Message + Default, 

Atomically retrieve then update a value.

pub fn insert<K, V, T>(&self, key: K, value: V) -> Result<Option<T>> where
    K: AsRef<[u8]>,
    V: Into<T>,
    T: Message + Default, 

Insert a value into the database.
