Enum SendError 

pub enum SendError {
    NotConnected,
    Empty,
    PayloadTooLarge,
    QueueFull,
}

Why a message was not accepted for sending.

Variants

NotConnected

The session is not open: not yet connected, or already closed or failed.

Empty

The message has no bytes.

PayloadTooLarge

The message is longer than SendConfig::max_payload.

QueueFull

The packet or byte budget is used up (backpressure).

impl Eq for SendError

impl Error for SendError

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.

impl PartialEq for SendError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
