Struct SessionId 

pub struct SessionId(/* private fields */);

Opaque identity of one opened-root lifetime.

This process-local value prevents a cursor or expected version from one open from being accepted by another whose sequence happens to match. It is not a credential and is never persisted.

Implementations

impl SessionId

pub const fn opaque(self) -> u64

Return the process-local opaque value for a language or wire adapter.

This value is an identity, not a credential. Consumers should preserve it exactly and must not infer ordering or lifetime from it.

pub const fn from_opaque(value: u64) -> Option<Self>

Recover an opaque session identity previously returned by Self::opaque.

Zero is reserved and never identifies a live opened root.
