Enum SslIoError 

pub enum SslIoError {
    WantRead,
    WantWrite,
    ZeroReturn,
    Syscall(ErrorStack),
    Ssl(ErrorStack),
    Other(i32),
}

Error returned by non-blocking SSL I/O operations.

WantRead / WantWrite indicate that the operation should be retried after the underlying BIO becomes ready. For in-memory BIO pairs, retrying immediately after driving the peer is sufficient.

Variants

WantRead

Retry after data arrives on the read BIO (SSL_ERROR_WANT_READ).

WantWrite

Retry after the write BIO drains (SSL_ERROR_WANT_WRITE).

ZeroReturn

The peer closed the connection cleanly (SSL_ERROR_ZERO_RETURN).

Syscall(ErrorStack)

Underlying I/O error; see ErrorStack for details (SSL_ERROR_SYSCALL).

Ssl(ErrorStack)

OpenSSL protocol error (SSL_ERROR_SSL).

Other(i32)

Unexpected error code returned by SSL_get_error.

Trait Implementations

impl Error for SslIoError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
