Enum SplitPolicy 

pub enum SplitPolicy {
    Shared,
    Owned,
}

Controls how Bytes::split behaves when the allocation can’t be split in place.

Variants

Shared

Prefer zero-copy splits, allowing the allocation to be shared behind an Arc when it can’t be split natively.

Mutating a resulting half then triggers a copy-on-write. This is the best choice for read-only or clone-heavy use cases, where the extra copy is never paid.

Owned

Ensure both halves are independently owned, copying eagerly when a native split isn’t possible.

This avoids a later copy-on-write surprise when the halves will be mutated. Prefer it when you split in order to mutate, so the copy is paid once, up front, instead of lazily on first write.
