Bytes::with_vtable Can it be opened for external use

[xiaxiangjun]

Just want to use it to use shared memory, but it pub(crate) unsafe fn with_vtable and pub(crate) struct Vtable, Hope to change to remote (crate)

[xiaxiangjun]

path: src/bytes.rs:102

pub(crate) struct Vtable
// Change to
pub struct Vtable

path: src/bytes.rs:478

pub(crate) unsafe fn with_vtable
// Change to
pub unsafe fn with_vtable

path: src/lib.rs:92

// add
pub use crate::bytes::Vtable;

Why not open a PR then?

[seanmonstar]

It is an eventual goal to make it public, but there are unresolved questions around forwards-compatibility.

• Is the current vtable all the functions that are needed?
• If we identify a new function later, how can we add it to the vtable without breaking people?
