Enum Event 

#[non_exhaustive]
pub enum Event {
    ConnectionStateChange(ConnectionState),
    SelectedCandidatePairChange(Box<Candidate>, Box<Candidate>),
    RoleChange(bool),
}

What the agent reports to its caller.

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.

ConnectionStateChange(ConnectionState)

The agent’s connection state changed.

SelectedCandidatePairChange(Box<Candidate>, Box<Candidate>)

A new pair was selected, carrying the local and remote candidates.

Media should be sent on this pair from now on.

RoleChange(bool)

Emitted when the ICE role switches due to a role conflict (RFC 8445 §7.3.1.1). The bool is true if the agent is now controlling, false if now controlled.
