[−][src]Struct structural::mut_ref::MutRef

#[repr(transparent)]
pub struct MutRef<'a, T: ?Sized> {
    pub ptr: *mut T,
    // some fields omitted
}

A wrapper type that associates a mutable raw pointer with a lifetime.

Motivation

This type was declared to pass a mutable-reference-like type to multiple methods to borrow multiple fields individually. If those methods took in mutable references it would cause undefined behavior to borrow multiple fields mutably, since each call borrows the entire data structure.

Fields

ptr: *mut T

Methods
