Struct mlua::SerializeOptions

#[non_exhaustive]
pub struct SerializeOptions {
    pub set_array_metatable: bool,
    pub serialize_none_to_null: bool,
    pub serialize_unit_to_null: bool,
}

A struct with options to change default serializer behaviour.

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.

set_array_metatable: bool

If true, sequence serialization to a Lua table will create table with the array_metatable attached.

Default: true

serialize_none_to_null: bool

If true, serialize None (part of Option type) to null. Otherwise it will be set to Lua Nil.

Default: true

serialize_unit_to_null: bool

If true, serialize Unit (type of () in Rust) and Unit structs to null. Otherwise it will be set to Lua Nil.

Default: true
