[src]

impl<T> From<T> for T[src]

impl<T, U> TryFrom<U> for T where
    U: Into<T>, 
[src]

type Error = Infallible

The type returned in the event of a conversion error.

impl<T, U> TryInto<U> for T where
    U: TryFrom<T>, 
[src]

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

impl<T> BorrowMut<T> for T where
    T: ?Sized
[src]

impl<T> Borrow<T> for T where
    T: ?Sized
[src]

impl<T> Any for T where
    T: 'static + ?Sized
[src]

impl<T, G> StorageValue<T> for G where
    G: StorageValue<T>,
    T: FullCodec
[src]

type Query = <G as StorageValue<T>>::Query

The type that get/take return.

fn append<Items, Item, EncodeLikeItem>(items: Items) -> Result<(), &'static str> where
    EncodeLikeItem: EncodeLike<Item>,
    Item: Encode,
    Items: IntoIterator<Item = EncodeLikeItem>,
    T: EncodeAppend<Item = Item>,
    <Items as IntoIterator>::IntoIter: ExactSizeIterator
[src]

Append the given items to the value in the storage.

T is required to implement codec::EncodeAppend.

fn append_or_put<Items, Item, EncodeLikeItem>(items: Items) where
    EncodeLikeItem: EncodeLike<Item>,
    Item: Encode,
    Items: IntoIterator<Item = EncodeLikeItem> + Clone + EncodeLike<T>,
    T: EncodeAppend<Item = Item>,
    <Items as IntoIterator>::IntoIter: ExactSizeIterator
[src]

Safely append the given items to the value in the storage. If a codec error occurs, then the old (presumably corrupt) value is replaced with the given items.

T is required to implement codec::EncodeAppend.

fn decode_len() -> Result<usize, &'static str> where
    T: DecodeLength + Len
[src]

Read the length of the value in a fast way, without decoding the entire value.

T is required to implement Codec::DecodeLength.

Note that 0 is returned as the default value if no encoded value exists at the given key. Therefore, this function cannot be used as a sign of existence. use the ::exists() function for this purpose.
