Struct WriteTraffic

pub struct WriteTraffic<'c, Data> { /* private fields */ }

Allows encrypting app-data

Implementations

impl<Data> WriteTraffic<'_, Data>

pub fn encrypt( &mut self, application_data: &[u8], outgoing_tls: &mut [u8], ) -> Result<usize, EncryptError>

Encrypts application_data into the outgoing_tls buffer

Returns the number of bytes that were written into outgoing_tls, or an error if the provided buffer is too small. In the error case, outgoing_tls is not modified

pub fn queue_close_notify( &mut self, outgoing_tls: &mut [u8], ) -> Result<usize, EncryptError>

Encrypts a close_notify warning alert in outgoing_tls

Returns the number of bytes that were written into outgoing_tls, or an error if the provided buffer is too small. In the error case, outgoing_tls is not modified

pub fn refresh_traffic_keys(self) -> Result<(), Error>

Arranges for a TLS1.3 key_update to be sent.

This consumes the WriteTraffic state: to actually send the message, call UnbufferedConnectionCommon::process_tls_records again which will return a ConnectionState::EncodeTlsData that emits the key_update message.

See ConnectionCommon::refresh_traffic_keys() for full documentation, including why you might call this and in what circumstances it will fail.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
