- Span<T> provides a type-safe and memory-safe representation of a contiguous region of arbitrary memory.
- Span<T> is a lightweight, stack-allocated (rather than heap) alternative to the array type and can be used to avoid unnecessary memory allocation and garbage collection.
- Span<T> has several useful methods for manipulating data, such as Slice and CopyTo, which allow for easy manipulation of subarrays.
- The main advantage of using Span<T> is that it allows for more efficient memory management, as it does not require allocating new memory when working with large data sets. Additionally, Span<T> also provides a number of safety features, such as bounds checking, to help prevent common programming errors.
- For spans that represent immutable or read-only structures, use System.ReadOnlySpan<T>
