Enum Error 

#[non_exhaustive]
pub enum Error {
    Stale(StreamId),
    AlreadyClaimed(Ticket),
    Full {
        capacity: usize,
    },
    PayloadFull {
        requested_slots: usize,
    },
    PayloadTooLarge {
        len: usize,
        capacity: usize,
    },
    Malformed(String),
    Closed,
    Reset,
    PeerGone,
    WouldBlock,
    Io(Error),
}

Additions are expected: a cause discovered later lands here rather than in a new major version, so a caller matches what it handles and leaves the rest to a catch-all.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stale(StreamId)

The address names a slot nothing occupies, or a generation that ended.

AlreadyClaimed(Ticket)

That side of the stream is already held, or was held and released.

Full

Every slot in this process’s lane is in use.

Fields

capacity: usize

PayloadFull

The producer’s payload arena has no contiguous run large enough.

Fields

requested_slots: usize

PayloadTooLarge

One chunk cannot fit in a lane of the selected payload arena.

Fields

len: usize

capacity: usize

Malformed(String)

The text or id is not a stream address.

Closed

This write half was shut down; nothing more goes in.

Reset

The other end reset the direction; buffered bytes were discarded.

PeerGone

The other end’s reader is gone; nothing written here will be read.

WouldBlock

Nothing to read, or no room to write, right now.

Io(Error)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<E> From<Error> for DispatchError<E>

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.
