Trait gdnative::export::user_data::Map

pub trait Map: UserData {
    type Err: Error;

    // Required method
    fn map<F, U>(&self, op: F) -> Result<U, Self::Err>
       where F: FnOnce(&Self::Target) -> U;
}

Trait for wrappers that can be mapped immutably.

Required Associated Types

type Err: Error

Required Methods

fn map<F, U>(&self, op: F) -> Result<U, Self::Err>

where F: FnOnce(&Self::Target) -> U,

Maps a &T to U. Called for methods that take &self.

Implementations of this method must not panic. Failures should be indicated by returning Err.
