Enum Event 

pub enum Event {
    Synced {
        max_block_size: u16,
        protocol_version: String,
    },
    Ack(u8),
    ResendRequested(u8),

        got: u8,
    },
    Timeout {

}

Things the session emits to the caller as parsed bytes arrive.

Variants

Synced

Sync handshake completed. Carries the device’s reported block size and protocol version.

Fields

max_block_size: u16

Device-advertised maximum payload bytes per packet.

protocol_version: String

Device-advertised protocol version string.

Ack(u8)

An ok<n> line was received, acknowledging the packet with sync n.

ResendRequested(u8)

A rs<n> line was received: the device is requesting we retransmit the packet with sync n.

AsciiLine(String)

A line was received that did not match any known control token. The file-transfer layer consumes these to parse PFT:* replies.

FatalError

A fe line was received: device reports a fatal protocol error.

OutOfSync

The session received an ok<m> whose number did not match the in-flight packet’s sync. Recovery requires calling Session::reset then Session::connect — the protocol has no way to resynchronise mid-stream.

Fields

expected: u8

Sync number we expected an ack for.

got: u8

Sync number the device acked.

Timeout

A queued packet exceeded its total retransmit budget without an ack. The packet has been dropped from the queue.

Fields

sync: u8

Sync number of the packet that timed out.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Event

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Event

fn eq(&self, other: &Event) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
