}Expand description
Trait that allows zero-copy write of value-references to slices in LE format.
Implementations should override using_encoded for value types and encode_to and size_hint for allocating types.
Wrapper types should override all methods.
Provided Methods§
sourcefn size_hint(&self) -> usize
fn size_hint(&self) -> usize
If possible give a hint of expected size of the encoding.
This method is used inside default implementation of encode
to avoid re-allocations.
sourcefn encode_to<T: Output + ?Sized>(&self, dest: &mut T)
fn encode_to<T: Output + ?Sized>(&self, dest: &mut T)
Convert self to a slice and append it to the destination.
sourcefn using_encoded<R, F: FnOnce(&[u8]) -> R>(&self, f: F) -> R
fn using_encoded<R, F: FnOnce(&[u8]) -> R>(&self, f: F) -> R
Convert self to a slice and then invoke the given closure with it.
sourcefn encoded_size(&self) -> usize
fn encoded_size(&self) -> usize
Object Safety§
This trait is not object safe.
