Enum Outcome 

pub enum Outcome {
    Exit {
        code: i32,
    },
    TransportClosed,
    WriterFailed,
    InitializeFailed,
}

How one connection ended.

Serving a Server or Client connection resolves to exactly one Outcome or to a transport Error; it never terminates the process. A server binary maps its outcome to a process disposition itself — Outcome::code reports the exit code the LSP lifecycle implies.

Variants

Exit

The endpoint processed exit. For a Server, code is 0 when the peer sent shutdown first and 1 otherwise; a Client permits local exit only after its shutdown request succeeds and therefore reports 0.

Fields

code: i32

The process exit code prescribed by the LSP lifecycle.

TransportClosed

The transport ended before exit, or a Client disconnected locally.

WriterFailed

The outbound path failed terminally: the writer failed, or required protocol traffic could not fit within the configured queue budgets.

InitializeFailed

A failed initialize transaction terminated the connection after its fixed error response was enqueued (ADR 0018).

Implementations

impl Outcome

pub fn code(&self) -> i32

The process exit code this outcome implies for a server binary: the LSP-defined code after exit, and 1 for every ending without one.
