Enum SendError 

pub enum SendError {
    NoSuchFlow(FlowId),
    NotAHop {
        got: &'static str,
    },
    MailboxFull {
        flow: FlowId,
        reason: MailboxFullReason,
    },
}

Why Runtime::send could not deliver a hop.

Variants

NoSuchFlow(FlowId)

NotAHop

Atomic Hop rule: only crate::Value::Message may cross Send.

Fields

got: &'static str

MailboxFull

Target inbox is at one of its logical bounds (OverflowPolicy::Reject). reason says which — see MailboxFullReason.

Fields

flow: FlowId

reason: MailboxFullReason

Trait Implementations

impl Clone for SendError

fn clone(&self) -> SendError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SendError

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

Formats the value using the given formatter.

impl Display for SendError

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

Formats the value using the given formatter.

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: &SendError) -> bool

Equality operator ==.

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

Inequality operator !=.
