Trait BorrowPessimize 

pub trait BorrowPessimize: PessimizeCast {
    type BorrowedPessimize: Pessimize;

    // Required methods
    fn with_pessimize(&self, f: impl FnOnce(&Self::BorrowedPessimize));
    fn assume_accessed_impl(&mut self);
}

Extract references to Pessimize values from references to Self (Pessimize impl helper)

Required Associated Types

type BorrowedPessimize: Pessimize

Pessimize type to which a reference can be extracted from &self

Required Methods

fn with_pessimize(&self, f: impl FnOnce(&Self::BorrowedPessimize))

Extract an &Pessimized from &self and all the provided operation on it.

In the common case where Self: Copy, you can implement this by calling pessimize::impl_with_pessimize_via_copy.

fn assume_accessed_impl(&mut self)

Extract an &mut Pessimized from &mut self, call assume_accessed on it, and propagate any “changes” back to the original &mut self.

In the common case where there is a cheap way to go from an &mut Self to a Self or Self::Pessimized, you can implement this by calling one of the pessimize::impl_assume_accessed_via_xyz functions.

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.
