Trait ExtendFromWithinUnchecked

pub trait ExtendFromWithinUnchecked {
    // Required method
    unsafe fn extend_from_within_unchecked<R>(&mut self, src: R)
       where R: RangeBounds<usize>;
}

A trait for extend_from_within without the capacity and bounds checks.

Required Methods

unsafe fn extend_from_within_unchecked<R>(&mut self, src: R)

where R: RangeBounds<usize>,

Copies elements from src range to the end of the collection without the capacity check and the bounds check for the range.

Safety

src must be a valid index for the collection. The capacity of the collection must be sufficient for the new items.

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.
