Trait FromLua

pub trait FromLua<'lua>: Sized {
    // Required method
    fn from_lua(
        lua_value: Value<'lua>,
        lua: Context<'lua>,
    ) -> Result<Self, Error>;
}

Trait for types convertible from Value.

Required Methods

fn from_lua(lua_value: Value<'lua>, lua: Context<'lua>) -> Result<Self, Error>

Performs the conversion.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
