Why a message was not sent.

Variants

Empty

Address(String)

The recipient names no one (the reason).

Malformed

A field well_formed refuses: every reader would drop the line.

Window

The sender’s window to this recipient is full (window_for): outstanding of its messages there are unread, as many as window allows, or, under pace Rate or Floor, V1_RATE_MS admits the next one in wait ms. Also a message stamped before one already admitted that it would push out (a clock that stepped back, a send that took the lock later). to as a command names it (Address::name).

Fields

to: String

outstanding: usize

window: usize

pace: Pace

wait: Option<i64>

Share

The sender’s unread messages to this recipient fill what the log keeps of its node’s messages (MEMBER_BYTES): this one would push the oldest out before it is shown. to as a command names it.

Fields

to: String

unread: usize

Steer

A steer for another node from a node the held membership does not let steer (steer_right).

Fields

kind: Kind

why: NoSteer

Reads

The recipient’s node reads message lines only up to format v (presence::reads, from its last session with this node), older than this message’s: it would never be shown there, and as no one there acknowledges it, it would hold the sender’s window (window_for) for TTL_MS. to as a command names it.

Fields

to: String

v: u8

Io(Error)

Trait Implementations

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 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 From<Error> for SendError

fn from(e: Error) -> Self

Converts to this type from the input type.
