Trait DecodeTrace 

pub trait DecodeTrace<'de, M, A>: Sized
where
    A: Allocator,
{
    // Required method
    fn trace_decode<D>(decoder: D) -> Result<Self, D::Error>
       where D: Decoder<'de, Mode = M, Allocator = A>;
}

Trait governing how types are decoded 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_decode<D>(decoder: D) -> Result<Self, D::Error>

where D: Decoder<'de, Mode = M, Allocator = A>,

Decode the given input.

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, K, V, A, M, S> DecodeTrace<'de, M, A> for HashMap<K, V, S>

where A: Allocator, K: Display + Decode<'de, M, A> + Eq + Hash, V: Decode<'de, M, A>, S: BuildHasher + Default,

Available on crate feature std only.

fn trace_decode<D>(decoder: D) -> Result<Self, D::Error>

where D: Decoder<'de, Mode = M, Allocator = A>,

impl<'de, K, V, A, M> DecodeTrace<'de, M, A> for BTreeMap<K, V>

where A: Allocator, K: Display + Decode<'de, M, A> + Ord, V: Decode<'de, M, A>,

fn trace_decode<D>(decoder: D) -> Result<Self, D::Error>
