Implementations

source

impl<'a, T, S> DequeStore<'a, T, S, Bincode2> where
T: Serialize + DeserializeOwned,
S: ReadonlyStorage,

source

pub fn attach(storage: &'a S) -> Option<StdResult<Self>>

Try to use the provided storage as an DequeStore.

Returns None if the provided storage doesn’t seem like an DequeStore. Returns Err if the contents of the storage can not be parsed.

source

impl<'a, T, S, Ser> DequeStore<'a, T, S, Ser> where
 T: Serialize + DeserializeOwned,
 S: ReadonlyStorage,
 Ser: Serde,

source

pub fn attach_with_serialization(
storage: &'a S,
_ser: Ser
) -> Option<StdResult<Self>>

Try to use the provided storage as an DequeStore. This method allows choosing the serialization format you want to use.

Returns None if the provided storage doesn’t seem like an DequeStore. Returns Err if the contents of the storage can not be parsed.

source

pub fn iter(&self) -> Iter<'a, T, S, Ser>ⓘNotable traits for Iter<'a, T, S, Ser>`impl<'a, T, S, Ser> Iterator for Iter<'a, T, S, Ser> where T: Serialize + DeserializeOwned, S: ReadonlyStorage, Ser: Serde, type Item = StdResult<T>;`

Return an iterator over the items in the collection

source

pub fn get_at(&self, pos: u32) -> StdResult<T>

Get the value stored at a given position.

Errors

Will return an error if pos is out of bounds or if an item is not found.
