Trait EncodeTrace 

pub trait EncodeTrace<M> {
    // Required method
    fn trace_encode<E>(&self, encoder: E) -> Result<(), E::Error>
       where E: Encoder<Mode = M>;

    // Provided method
    fn size_hint(&self) -> Option<usize> { ... }
}

Trait governing how types are encoded specifically for tracing.

This is used for types where some extra bounds might be necessary to trace a container such as a HashMap<K, V> where K would have to implement fmt::Display.

Required Methods

fn trace_encode<E>(&self, encoder: E) -> Result<(), E::Error>

where E: Encoder<Mode = M>,

Encode the given output.

Provided Methods

fn size_hint(&self) -> Option<usize>

The number of fields in the type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<'de, M, K, V, S> EncodeTrace<M> for HashMap<K, V, S>
