Struct TelepathServer 

pub struct TelepathServer<T, const N: usize> { /* private fields */ }

RPC server that runs on the target MCU.

T is the transport type implementing transport::Transport. N is the size of the internal receive accumulator and transmit buffers.

Type parameter guidance

Choose N ≥ 512 to accommodate a max-payload frame with COBS overhead.

Implementations

impl<T, const N: usize> TelepathServer<T, N>

pub fn new(transport: T, commands: &'static [CommandMetadata]) -> Self

Create a new server with the given transport and command registry.

pub fn resource<R: 'static>(self, val: R) -> Self

Register a resource for #[resource] injection.

The value is moved into the server’s internal registry and made available to command shims that declare a matching #[resource] parameter.

pub fn find_command(&self, id: u16) -> Option<&CommandMetadata>

Look up a command by its ID using linear scan.

Linear scan is intentional: embedded command counts are typically ≤ 64, making hash-map overhead unjustified.

pub fn dispatch( &mut self, cmd_id: u16, input: &[u8], output: &mut [u8], ) -> Result<usize, DispatchError>

Dispatch a pre-decoded payload slice to the matching command handler.

Returns the number of bytes written to output on success.

impl<T: Transport, const N: usize> TelepathServer<T, N>

pub fn poll(&mut self)

Process any pending bytes from the transport.

Call this in a tight loop. Reads all available bytes, accumulates them into COBS frames, and sends a response for each complete request.
