Trait MergePatchNullableFields 

pub trait MergePatchNullableFields {
    // Required method
    fn is_nullable(field: &str) -> bool;
}

A merge patch model: which of its fields a client may set to null (its Patch fields), as opposed to leaving them out.

Implemented by #[derive(MergePatchNullableFields)], from each field’s PatchKind. A field that may be cleared is a Patch<T>; Option<Option<T>> is not supported, and the derive rejects it.

Required Methods

fn is_nullable(field: &str) -> bool

Whether the field named field may be set to null.

Dyn Compatibility

This trait is not dyn compatible.

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