Trait Implementations

impl<E> Clone for FnEncode<E> where
    E: Clone + Encode + 'static, 

pub fn clone(&self) -> FnEncode<E>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E> Debug for FnEncode<E> where
    E: Debug + Encode, 

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<E> Encode for FnEncode<E> where
    E: Encode, 

pub fn encode_to<W>(&self, dest: &mut W) where
    W: Output, 

Convert self to a slice and append it to the destination.

pub fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

pub fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

pub fn using_encoded<R, F>(&self, f: F) -> R where
    F: FnOnce(&[u8]) -> R,
