Expand description

Extension trait for reading GPSD JSON responses from a buffered reader

This trait provides functionality to read and parse GPSD JSON messages from any type that implements BufRead. Messages are expected to be newline-delimited JSON objects.

Provided Methods§

Source

fn read_response<Response>( &mut self, buf: &mut Vec<u8>, ) -> Result<Option<Response>>
where Response: GpsdJsonResponse,

Reads and deserializes a single GPSD response message

§Arguments
  • buf - A reusable string buffer for reading data
§Returns
  • Ok(Some(response)) - Successfully parsed response message
  • Ok(None) - End of stream reached
  • Err(_) - I/O or parsing error occurred
§Example
let mut buf = Vec::new();
if let Ok(Some(response)) = reader.read_response::<ResponseMessage>(&mut buf) {
    // Process the response
}

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
