Variants

NotConnected

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

No server is currently connected to this client.

Connected(Bridge<'a>)

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

A server is connected and available for requests.

InUse

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

Access to the bridge is being exclusively acquired (e.g., during BridgeState::with).

Implementations

impl BridgeState<'_>

fn with<R>(f: impl FnOnce(&mut BridgeState<'_>) -> R) -> R

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

Take exclusive control of the thread-local BridgeState, and pass it to f, mutably. The state will be restored after f exits, even by panic, including modifications made to it by f.

N.B., while f is running, the thread-local state is BridgeState::InUse.
