Struct ProcMacroServerProcess 

pub(crate) struct ProcMacroServerProcess {
    state: Mutex<ProcessSrvState>,
    version: u32,
    protocol: Protocol,
    exited: OnceLock<AssertUnwindSafe<ServerError>>,
    active: AtomicU32,
}

Represents a process handling proc-macro communication.

Fields

state: Mutex<ProcessSrvState>

The state of the proc-macro server process, the protocol is currently strictly sequential hence the lock on the state.

version: u32

protocol: Protocol

exited: OnceLock<AssertUnwindSafe<ServerError>>

Populated when the server exits.

active: AtomicU32

Implementations

impl ProcMacroServerProcess

pub(crate) fn spawn<'a>( process_path: &AbsPath, env: impl IntoIterator<Item = (impl AsRef<OsStr>, &'a Option<impl 'a + AsRef<OsStr>>)> + Clone, version: Option<&Version>, ) -> Result<ProcMacroServerProcess>

Starts the proc-macro server and performs a version check

pub(crate) fn run( spawn: impl Fn(Option<ProtocolFormat>) -> Result<(Box<dyn ProcessExit>, Box<dyn Write + Send + Sync>, Box<dyn BufRead + Send + Sync>)>, version: Option<&Version>, binary_server_version: impl Fn() -> String, ) -> Result<ProcMacroServerProcess>

Invokes spawn and performs a version check.

pub(crate) fn find_proc_macros( &self, dylib_path: &AbsPath, ) -> Result<Result<Vec<(String, ProcMacroKind)>, String>, ServerError>

Finds proc-macros in a given dynamic library.

pub(crate) fn exited(&self) -> Option<&ServerError>

Returns the server error if the process has exited.

pub(crate) fn version(&self) -> u32

Retrieves the API version of the proc-macro server.

pub(crate) fn rust_analyzer_spans(&self) -> bool

Enable support for rust-analyzer span mode if the server supports it.

fn version_check( &self, callback: Option<SubCallback<'_>>, ) -> Result<u32, ServerError>

Checks the API version of the running proc-macro server.

fn enable_rust_analyzer_spans( &self, callback: Option<SubCallback<'_>>, ) -> Result<SpanMode, ServerError>

Enable support for rust-analyzer span mode if the server supports it.

pub(crate) fn expand( &self, proc_macro: &ProcMacro, subtree: SubtreeView<'_>, attr: Option<SubtreeView<'_>>, env: Vec<(String, String)>, def_site: Span, call_site: Span, mixed_site: Span, current_dir: String, callback: Option<SubCallback<'_>>, ) -> Result<Result<TopSubtree, String>, ServerError>

pub(crate) fn send_task_legacy<Request, Response>( &self, send: impl FnOnce(&mut dyn Write, &mut dyn BufRead, Request, &mut String) -> Result<Option<Response>, ServerError>, req: Request, ) -> Result<Response, ServerError>

fn with_locked_io<R, B>( &self, buf: B, f: impl FnOnce(&mut dyn Write, &mut dyn BufRead, &mut B) -> Result<R, ServerError>, ) -> Result<R, ServerError>

pub(crate) fn run_bidirectional( &self, initial: BidirectionalMessage, callback: SubCallback<'_>, ) -> Result<BidirectionalMessage, ServerError>

pub(crate) fn number_of_active_req(&self) -> u32
