结构体 WriteTraffic 

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

允许加密应用数据

实现

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 缓冲区

返回数量 bytes that were written into outgoing_tls, 或 an error if the provided 缓冲区 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 一个 close_notify warning alert in outgoing_tls

返回数量 bytes that were written into outgoing_tls, 或 an error if the provided 缓冲区 is too small. In the error case, outgoing_tls is not modified

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

Arranges 用于 一个 TLS 1.3 key_update 到 be sent.

This consumes the WriteTraffic state: 到 actually send the message, call UnbufferedConnectionCommon::process_tls_records again which will return 一个 ConnectionState::EncodeTlsData that emits the key_update message.

，请参见ConnectionCommon::refresh_traffic_keys() 用于 full documentation, including why you might call this 并 in what circumstances it will fail.
