Enum Instruction

pub enum Instruction {
    SendMessage(Vec<u8>),
    SendMessageDependingOnLastReceivedMessage(fn(Option<Vec<u8>>) -> Option<Vec<u8>>),
    ReceiveMessage,
    ReceiveMessageWithMaxSize(usize),
    StopExchange,
}

Type of network instruction executed by the server mocker.

Variants

SendMessage(Vec<u8>)

Send given message to the client

SendMessageDependingOnLastReceivedMessage(fn(Option<Vec<u8>>) -> Option<Vec<u8>>)

Send a message to the client depending on the last received message

If the given function returns None, no message is sent

Example

SendMessageDependingOnLastReceivedMessage(|last_received_message: Option<Vec<u8>>| {
  if let Some(last_received_message) = last_received_message {
    if last_received_message == vec![0x01, 0x02, 0x03] {
      Some(vec![0x04, 0x05, 0x06])
    } else {
      None
    }
  } else {
    None
  }
});

ReceiveMessage

Wait for a message to be received.

The message could be recovered with ServerMocker::pop_received_message

ReceiveMessageWithMaxSize(usize)

Wait for a message to be received with a maximum size (useful in UDP).

If the message is bigger than the given size, the message is truncated.

The message could be recovered with ServerMocker::pop_received_message

StopExchange

Stop the exchange with the client, close the connection in case of TCP

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Instruction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instruction

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

Formats the value using the given formatter.

impl PartialEq for Instruction

fn eq(&self, other: &Instruction) -> 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.

impl StructuralPartialEq for Instruction
