Implementations

source

impl<'a, T: ReadonlyStorage> ReadonlyPrefixedStorage<'a, T>

source

pub fn new(namespace: &[u8 ], storage: &'a T) -> Self

source

pub fn multilevel(namespaces: &[&[u8 ]], storage: &'a T) -> Self

Trait Implementations

source

impl<'a, T: ReadonlyStorage> ReadonlyStorage for ReadonlyPrefixedStorage<'a, T>

source

fn range<'b>(
 &'b self,
 start: Option<&[u8 ]>,
 end: Option<&[u8 ]>,
 order: Order
) -> Box<dyn Iterator<Item = KV> + 'b>

range allows iteration over a set of keys, either forwards or backwards

source

fn get(&self, key: &[u8 ]) -> Option<Vec<u8>>

Returns None when key does not exist. Returns Some(Vec) when key exists. Read more
