}Expand description
Trait that allows zero-copy read of value-references from slices in LE format.
Required Methods§
Provided Methods§
sourcefn skip<I>(input: &mut I) -> Result<(), Error>where
I: Input,
fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,
Attempt to skip the encoded value from input.
The default implementation of this function is just calling Decode::decode.
When possible, an implementation should provide a specialized implementation.
sourcefn 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.
