FileWriter

sail::worker

Struct FileWriter 

Source 
pub struct FileWriter { /* private fields */ }
Expand description

A streaming write to a guest file. Chunks feed a bounded channel that backs the client-streaming RPC, so a slow uplink applies backpressure rather than buffering the source. The RPC result surfaces from FileWriter::finish.

Implementations§

Source§

impl FileWriter

Source

pub async fn write_chunk(&mut self, data: Vec<u8>) -> Result<(), SailError>

Send the next chunk of file data. If the RPC has already ended, returns its result instead.

Source

pub async fn finish(&mut self) -> Result<(), SailError>

Finish the write and return the RPC’s result, creating an empty file when no chunks were sent.
