Trait SerializeIgnoredFields 

pub trait SerializeIgnoredFields {
    type Key: ?Sized + Serialize;
    type Value: ?Sized + Serialize;

    // Required methods
    fn len(&self) -> usize;
    fn iter(&self) -> impl Iterator<Item = (&Self::Key, &Self::Value)>;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Trait for types that can be used to re-serialize ignored fields.

Required Associated Types

type Key: ?Sized + Serialize

The type of the key for the ignored fields.

type Value: ?Sized + Serialize

The type of the value of ignored fields.

Required Methods

fn len(&self) -> usize

The amount of ignored fields.

fn iter(&self) -> impl Iterator<Item = (&Self::Key, &Self::Value)>

Iterate over the ignored fields.

Provided Methods

fn is_empty(&self) -> bool

Check if there are exactly 0 ignored fields.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
