Trait Subsliceable 

pub unsafe trait Subsliceable: Slice {
    // Required method
    unsafe fn check_subslice(&self, start: usize, end: usize);

    // Provided methods
    unsafe fn check_advance(&self, offset: usize) { ... }
    unsafe fn check_truncate(&self, len: usize) { ... }
    unsafe fn check_split(&self, at: usize) { ... }
}

A slice that can be split into smaller subslices.

Safety

If Self::check_subslice (or other derived methods) doesn’t panic, then the subslice with the given range must be valid.

Required Methods

unsafe fn check_subslice(&self, start: usize, end: usize)

Check if a subslice is valid.

Safety

start..end must be a valid range of the item slice returned by Slice::to_slice.

Provided Methods

unsafe fn check_advance(&self, offset: usize)

Same as self.check_subslice(offset, self.to_slice().len()).

Safety

See Self::check_subslice.

unsafe fn check_truncate(&self, len: usize)

Same as self.check_subslice(0, offset)).

Safety

See Self::check_subslice.

unsafe fn check_split(&self, at: usize)

Same as { self.check_subslice(0, at)); self.check_subslice(at, self.to_slice().len()) }.

Safety

See Self::check_subslice.

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.
