Enum AmqpError 

#[non_exhaustive]
pub enum AmqpError {
    Connect(Box<dyn StdError + Send + Sync>),
    Publish(Box<dyn StdError + Send + Sync>),
    Subscribe(Box<dyn StdError + Send + Sync>),
    Consume(Box<dyn StdError + Send + Sync>),
    Declare(Box<dyn StdError + Send + Sync>),
    Request(Box<dyn StdError + Send + Sync>),

    Transaction(String),
    InvalidOptions(String),
}

Errors returned by LapinBroker and the types it hands out.

Underlying lapin errors are boxed as sources so the client library does not leak into this crate’s public API surface.

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.

Connect(Box<dyn StdError + Send + Sync>)

Establishing or closing the connection failed.

Publish(Box<dyn StdError + Send + Sync>)

Publishing a message failed, or the broker refused to confirm it.

Subscribe(Box<dyn StdError + Send + Sync>)

Opening a subscription (channel, QoS, or consume) failed.

Consume(Box<dyn StdError + Send + Sync>)

Receiving a delivery from an open consumer failed.

Declare(Box<dyn StdError + Send + Sync>)

Declaring the expected topology (exchange, queue, or binding) failed.

Request(Box<dyn StdError + Send + Sync>)

Sending a request or receiving its reply failed.

RequestTimeout(Duration)

No reply arrived within the caller’s deadline.

The pending request is dropped; a reply arriving later is discarded.

Closed

An operation ran against a connection that has already shut down.

The ladder makes misuse through the owner of the connected broker a compile error, so this reports the case it cannot cover: a handle aliasing the connection (a publisher paired before the shutdown, a requester clone) used afterwards, which must fail rather than silently succeed against a dead connection.

Fields

target: String

The routing key, queue, or exchange the operation targeted.

Transaction(String)

A transaction call ran out of order on a transactional publisher.

A commit or an abort with no open transaction, or a second begin while one is open. The message names the offending call.

InvalidOptions(String)

The requested combination of options cannot be executed.

The message names the offending option and the remediation.

Trait Implementations

impl Debug for AmqpError

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

Formats the value using the given formatter.

impl Display for AmqpError

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

Formats the value using the given formatter.

impl Error for AmqpError

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.
