Struct AsyncLineWriter 

pub struct AsyncLineWriter { /* private fields */ }

Asynchronous line writer that buffers writes on a background Tokio task.

The writer is Clone; all clones share the same background task. The task exits when all handles are dropped.

Implementations

impl AsyncLineWriter

pub fn new(path: PathBuf) -> Result<Self>

Create a new line writer that appends to path.

Spawns a background actor task that owns the file handle and performs all I/O via spawn_blocking. The file is created eagerly if it does not exist.

pub async fn new_async(path: PathBuf) -> Result<Self>

Create a new line writer without performing synchronous setup on the async executor.

pub fn write_line(&self, line: String)

Queue a line for writing. Drops the line if either bound is exhausted.

pub async fn flush(&self)

Flush pending writes and wait for completion.

pub async fn flush_result(&self) -> Result<()>

Flush pending writes and report whether the batch reached the file.

Self::flush remains the compatibility API for best-effort callers; this companion method lets lifecycle code and diagnostics distinguish a successful drain from a closed actor or failed file write.

pub fn diagnostics(&self) -> AsyncLineWriterDiagnostics
