Socket status.

This is used with the sn_sr method.

Variants

Closed = 0

Socket closed, this is the reset state of all sockets.

This state can be set by a Disconnect or Close command.

This state will also be set automatically if a timeout occurs.

Init = 19

The socket is opened in TCP mode.

This state is set when the socket protocol is Tcp, and a Open command is sent.

In this state you can use the Listen and Connect commands.

Listen = 20

The socket is listening, operating as a TCP server.

The socket will wait for a connextion-request (SYN packet) from a peer (TCP client).

The state will change to Established when the connection-request is successfully accepted. Otherwise the state will change to Closed after the TCP timeout duration set by rcr and rtr.

SynSent = 21

Connection request (SYN packet) has been sent to a peer.

This is temporarily displayed between the Init and Established states, after a Connect command has been sent.

If the SYN/ACK is received from the peer the state changes to Established, otherwise the state changes to Closed after the TCP timeout duration set by rcr and rtr.

SynRecv = 22

Connection request (SYN packet) has been received from a peer.

If the socket sends the response (SYN/ACK packet) to the peer successfully the state changes to Established, otherwise the state changes to Closed after the TCP timeout duration set by rcr and rtr.

Established = 23

TCP connection is established.

When operating as a TCP client this state is set after the TCP server accepts the SYN packet, which is sent by the client after issuing a Connect.

When operating as a TCP server this state is set after a client connects when in the Listen state.

While in this state data can be transferred with the Send and Recv commands.

FinWait = 24

Temporary status between status transitions.

This indicates the socket is closing.

Closing = 26

Temporary status between status transitions.

This indicates the socket is closing.

TimeWait = 27

Temporary status between status transitions.

This indicates the socket is closing.

CloseWait = 28

The socket has received the disconnect-request (FIN packet) from the connected peer.

This is half-closing status, and data can be transferred.

For full-closing the Disconnect command is used.

For just-closing the Close command is used.

LastAck = 29

Temporary status between status transitions.

Udp = 34

Socket is opened in UDP mode.

This state is set when the socket protocol is Udp, and a Open command is sent.

Macraw = 66

Socket is opened in MACRAW mode.

This is valid only for socket 0.

This state is set when the socket protocol is Macraw, and a Open command is sent.

Trait Implementations

impl Clone for SocketStatus

fn clone(&self) -> SocketStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SocketStatus

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

Formats the value using the given formatter.

impl Default for SocketStatus

fn default() -> SocketStatus

Returns the “default value” for a type.

impl Format for SocketStatus

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<SocketStatus> for u8

fn from(val: SocketStatus) -> u8

Converts to this type from the input type.

impl Hash for SocketStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SocketStatus

fn cmp(&self, other: &SocketStatus) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SocketStatus

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SocketStatus

fn partial_cmp(&self, other: &SocketStatus) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u8> for SocketStatus

type Error = u8

The type returned in the event of a conversion error.

fn try_from(val: u8) -> Result<SocketStatus, u8>

Performs the conversion.
