Trait LoadMultiple

pub trait LoadMultiple {
    type Item;

    // Required methods
    fn load_unchecked(&mut self) -> Result<(), MapError>;
    fn load_conditionally(
        &mut self,
        condition: impl Fn(&Self::Item) -> bool + Copy,
    ) -> Result<(), MapError>;

    // Provided method
    fn load(&mut self) -> Result<(), MapError> { ... }
}

Required Associated Types

type Item

Required Methods

fn load_unchecked(&mut self) -> Result<(), MapError>

fn load_conditionally( &mut self, condition: impl Fn(&Self::Item) -> bool + Copy, ) -> Result<(), MapError>

Provided Methods

fn load(&mut self) -> Result<(), MapError>

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.
