Enum SessionError 

pub enum SessionError {
    Io(Error),
    Protocol(String),
    Rejected(Metadata<'static>),
    NotResumable,
    ConnectTimeout,
}

Errors that can occur during session establishment or operation.

Implementations

impl SessionError

pub fn is_retryable(&self) -> bool

Returns true if a retry of the same connection attempt may succeed.

I/O errors and timeouts are transient — the remote might become available shortly. Protocol errors and explicit rejections are permanent for this peer address and will not resolve by retrying.

Trait Implementations

impl Debug for SessionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SessionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SessionError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
