Trait TrySlice 

trait TrySlice<T> {
    // Required methods
    fn try_mut<I>(&mut self, index: I) -> Result<&mut [T], Error>
       where I: SliceIndex<[T], Output = [T]>;
    fn try_ref<I>(&self, index: I) -> Result<&[T], Error>
       where I: SliceIndex<[T], Output = [T]>;
}

Slicing that reports a caller buffer sized too small, rather than panicking or silently truncating.

Required Methods

fn try_mut<I>(&mut self, index: I) -> Result<&mut [T], Error>

where I: SliceIndex<[T], Output = [T]>,

fn try_ref<I>(&self, index: I) -> Result<&[T], Error>

where I: SliceIndex<[T], Output = [T]>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
