Trait SerializeFilter 

pub trait SerializeFilter<T: ?Sized> {
    // Required methods
    fn skip(&self, field: Field<'_, T>) -> bool;
    fn filtered_len(&self, len: Option<usize>) -> Option<usize>;
}

Trait implemented by types which can be used to filter the serializable fields of another type.

Required Methods

fn skip(&self, field: Field<'_, T>) -> bool

Returns whether the specified field should be skipped.

fn filtered_len(&self, len: Option<usize>) -> Option<usize>

Returns the number of fields which will be serialized given the total field count.

Dyn Compatibility

This trait is dyn compatible.

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