source

pub fn multilevel(
namespaces: &[&[u8 ]],

) -> ReadonlyPrefixedStorage<'a, T>

Trait Implementations

source

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

source

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

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

source

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