Enum PfsFailure 

pub enum PfsFailure {
    Capacity,
    SessionMissing,
    Crypto,
    Send,
    Timeout,
    Other,
}

Why a local PFS negotiation step failed. Surfaced to applications via LocalNode::on_pfs_failed so a failed/stalled negotiation reports a reason instead of silently doing nothing.

Variants

Capacity

No free identity or peer slot to activate the ephemeral session — e.g. the MAC IDENTITIES/peer table is exhausted, or more concurrent PFS sessions were requested than there are ephemeral identity slots.

SessionMissing

A PFS response or teardown referenced a session that does not exist.

Crypto

Crypto failure while deriving the ephemeral session keys.

Send

Failed to transmit a PFS control frame to the peer.

Timeout

A sent PFS request was not answered before its deadline (the peer never responded, or its response was lost).

Other

Any other node-layer failure during PFS processing.

Trait Implementations

impl Clone for PfsFailure

fn clone(&self) -> PfsFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PfsFailure

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

Formats the value using the given formatter.

impl PartialEq for PfsFailure

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