Struct elrond_codec::Empty
source · pub struct Empty;Expand description
Empty structure with an empty bytes representation. Equivalent to false, 0 or [u8; 0], but more explicit.
Note: the unit type () would have naturally fit this role, but we decided to make the unit type multi-value only.

Version of
dep_decode that can handle errors as soon as they occur.
For instance in can exit immediately and make sure that if it returns, it is a success.
By not deferring error handling, this can lead to somewhat smaller bytecode. Read moresource§fn dep_decode<I: NestedDecodeInput>(input: &mut I) -> Result<Self, DecodeError>
fn dep_decode<I: NestedDecodeInput>(input: &mut I) -> Result<Self, DecodeError>
Attempt to deserialise the value from input,
using the format of an object nested inside another structure.
In case of success returns the deserialized value and the number of bytes consumed during the operation. Read more
