Struct TransportError 

#[non_exhaustive]
pub struct TransportError { /* private fields */ }

Why no response arrived, or why its body could not be read.

kind says where the exchange broke, and the boxed source is the transport’s own error, kept for its message and its chain. A custom HttpTransport builds one with new. Its class is Class::Network for every kind but TransportKind::Request, a request that could not be built, which is Class::InvalidRequest.

Implementations

impl TransportError

pub fn new( kind: TransportKind, source: impl Into<Box<dyn Error + Send + Sync>>, ) -> Self

A transport failure of kind, caused by source.

pub fn kind(&self) -> TransportKind

Where the exchange broke.

Trait Implementations

impl Classify for TransportError

fn class(&self) -> Class

The class of this error.

fn is_fault(&self) -> bool

Whether this error is a fault, rather than the venue answering as designed. False only for defined outcomes, such as a Fill-And-Kill order that matched nothing, or a venue that does not serve the caller’s region. Alerting should key on this; retrying should not.

fn retry_after(&self) -> Option<Duration>

How long the server asked the caller to wait. Defaults to the class’s own; an error whose wait outlives its class, such as a ban that says when it lifts, overrides it. Never Some of zero.

fn is_retriable(&self) -> bool

Whether retrying could plausibly succeed, read from the class (see Class::is_retriable).

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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<TransportError> for ApiError

fn from(source: TransportError) -> Self

Converts to this type from the input type.
