Trait mlua::FromLuaMulti

pub trait FromLuaMulti<'lua>: Sized {
    fn from_lua_multi(values: MultiValue<'lua>, lua: &'lua Lua) -> Result<Self>;
}

Trait for types that can be created from an arbitrary number of Lua values.

This is a generalization of FromLua, allowing an arbitrary number of Lua values to participate in the conversion. Any type that implements FromLua will automatically implement this trait.

Required Methods

fn from_lua_multi(values: MultiValue<'lua>, lua: &'lua Lua) -> Result<Self>

Performs the conversion.

In case values contains more values than needed to perform the conversion, the excess values should be ignored. This reflects the semantics of Lua when calling a function or assigning values. Similarly, if not enough values are given, conversions should assume that any missing values are nil.
