Struct mlua::serde::ser::Options

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

Available on crate feature serialize only.

A struct with options to change default serializer behavior.

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 the 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

detect_serde_json_arbitrary_precision: bool

If true, serialize serde_json::Number with arbitrary_precision to a Lua number. Otherwise it will be serialized as an object (what serde does).

Default: false

Implementations

impl Options

pub const fn new() -> Self

Returns a new instance of Options with default parameters.

pub const fn set_array_metatable(self, enabled: bool) -> Self

Sets set_array_metatable option.

pub const fn serialize_none_to_null(self, enabled: bool) -> Self

Sets serialize_none_to_null option.

pub const fn serialize_unit_to_null(self, enabled: bool) -> Self

Sets serialize_unit_to_null option.

pub const fn detect_serde_json_arbitrary_precision(self, enabled: bool) -> Self

Sets detect_serde_json_arbitrary_precision option.

This option is used to serialize serde_json::Number with arbitrary precision to a Lua number. Otherwise it will be serialized as an object (what serde does).

This option is disabled by default.

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Options

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Options

fn default() -> Self

Returns the “default value” for a type.
