Struct AddNullable

#[non_exhaustive]
pub struct AddNullable {
    pub remove_null_type: bool,
    pub add_const_null: bool,
}

Adds a "nullable": true property to schemas that allow null types.

This also applies to subschemas.

This is useful for dialects of JSON Schema (e.g. OpenAPI 3.0) that use nullable instead of explicit null types.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

remove_null_type: bool

When set to true (the default), "null" will also be removed from the schemas type.

add_const_null: bool

When set to true (the default), a schema that has a type only allowing null will also have the equivalent "const": null inserted.
