Delete a sequence of bytes of given
length
at an offset
from the backend.
This either sets the bytes in the given slice to zeroes, or if
offset
+ length
>= RandomAccess::len() is the same as
truncate(offset)
. Read moresource§fn truncate<'life0, 'async_trait>(

Resize the sequence of bytes so that RandomAccess::len() is set to
length
. If length
< RandomAccess::len(), the bytes are disregarded.
If length
> RandomAccess::len(), the storage is zero-padded. Read moresource§fn len<'life0, 'async_trait>(

Whether the storage is empty. For some storage backends it may be
cheaper to calculate whether the storage is empty than to calculate the
length. Read more
