Enum Phase 

#[non_exhaustive]
pub enum Phase {
    BeforeInitialize,
    AwaitingInitializeResult,
    AfterInitializeSuccess,
    AfterInitializeError,
    Ready,
}

The 2025-11-25 session lifecycle phase before a given event is processed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BeforeInitialize

No initialize request has been observed yet.

AwaitingInitializeResult

initialize was sent; the server has not yet responded to it.

AfterInitializeSuccess

The server answered initialize with a result; notifications/initialized has not yet been observed.

AfterInitializeError

The server answered initialize with an error; the session never became ready.

Ready

notifications/initialized has been observed; normal operation.
