Implementations

impl<'a, T> ReadonlyBucket<'a, T> where
    T: Serialize + DeserializeOwned
[src]

pub fn new(storage: &'a dyn Storage, namespace: &[u8]) -> Self[src]

pub fn multilevel(storage: &'a dyn Storage, namespaces: &[&[u8]]) -> Self[src]

pub fn load(&self, key: &[u8]) -> StdResult<T>[src]

load will return an error if no data is set at the given key, or on parse error

pub fn may_load(&self, key: &[u8]) -> StdResult<Option<T>>[src]

may_load will parse the data stored at the key if present, returns Ok(None) if no data there. returns an error on issues parsing
