Trait parity_scale_codec::Decode
source · [−]pub trait Decode: Sized {

}Expand description
Trait that allows zero-copy read of value-references from slices in LE format.
Required methods
Provided methods
Attempt to skip the encoded value from input.
The default implementation of this function is just calling Decode::decode.
When possible, an implementation should provided a specialized implementation.
fn encoded_fixed_size() -> Option<usize>
fn encoded_fixed_size() -> Option<usize>
Returns the fixed encoded size of the type.
If it returns Some(size) then all possible values of this
type have the given size (in bytes) when encoded.
NOTE: A type with a fixed encoded size may return None.
