Enum nmstate::MptcpAddressFlag

#[non_exhaustive]
pub enum MptcpAddressFlag {
    Signal,
    Subflow,
    Backup,
    Fullmesh,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Signal

The endpoint will be announced/signaled to each peer via an MPTCP ADD_ADDR sub-option. Upon reception of an ADD_ADDR sub-option, the peer can try to create additional subflows. Cannot used along with MptcpAddressFlag::Fullmesh as Linux kernel enforced.

Subflow

If additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow using this endpoint as the source address after the MPTCP connection is established.

Backup

If this is a subflow endpoint, the subflows created using this endpoint will have the backup flag set during the connection process. This flag instructs the peer to only send data on a given subflow when all non-backup subflows are unavailable. This does not affect outgoing data, where subflow priority is determined by the backup/non-backup flag received from the peer.

Fullmesh

If this is a subflow endpoint and additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow for each known peer address, using this endpoint as the source address. This will occur after the MPTCP connection is established. If the peer did not announce any additional addresses using the MPTCP ADD_ADDR sub-option, this will behave the same as a plain subflow endpoint. When the peer does announce addresses, each received ADD_ADDR sub-option will trigger creation of an additional subflow to generate a full mesh topology.

Trait Implementations

impl Clone for MptcpAddressFlag

fn clone(&self) -> MptcpAddressFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MptcpAddressFlag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MptcpAddressFlag

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for MptcpAddressFlag

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

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
