Trait WithBorrow

pub trait WithBorrow<'a, O> {
    // Required methods
    fn with_borrow<F, R>(&'a self, f: F) -> R
       where F: FnOnce(&O) -> R;
    fn with_borrow_mut<F, R>(&'a self, f: F) -> R
       where F: FnOnce(&mut O) -> R;
}

Required Methods

fn with_borrow<F, R>(&'a self, f: F) -> R

where F: FnOnce(&O) -> R,

fn with_borrow_mut<F, R>(&'a self, f: F) -> R

where F: FnOnce(&mut O) -> R,

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.
