Function tls_parser::tls_state_transition [−][src]
pub fn tls_state_transition(
state: TlsState,
msg: &TlsMessage<'_>,
to_server: bool
) -> Result<TlsState, StateChangeError>
Expand description
Update the TLS state machine, doing one transition
Given the previous state and the parsed message, return the new state or a state machine error.
This state machine only implements the TLS handshake.
Some transitions only check the new message type, while some others must match the content (for example, to check if the client asked to resume a session).
If the previous state is Invalid
, the state machine will not return an error, but keep the
same Invalid
state. This is used to raise error only once if the state machine keeps being
updated by new messages.
