    Http(String),
    Network(String),
    RateLimited,
    WouldExceedUserActionLimit {
        retry_after_ms: u64,
        needed: u32,

    Unavailable,
    Timeout,
    Rejected(String),
    Parse(String),
    Signing(String),
    Configuration(String),
    Unknown(String),
}

Errors returned by exchange operations.

Variants

Http(String)

HTTP status or response-level failure that does not fit a narrower case.

Network(String)

Network transport failure such as DNS, connection reset, or TLS failure.

RateLimited

Exchange rejected the request because a rate limit was hit.

WouldExceedUserActionLimit

Exchange action budget is too low for the requested batch.

Fields

retry_after_ms: u64

Milliseconds to wait before retrying.

needed: u32

Number of action credits the attempted operation needed.

Unavailable

Exchange is temporarily unavailable.

Timeout

Request exceeded its configured deadline.

Rejected(String)

Exchange accepted the request shape but rejected the order semantics.

Parse(String)

Adapter could not parse an exchange response.

Signing(String)

Request signing failed before submission.

Configuration(String)

Adapter was configured with invalid or missing settings.

Unknown(String)

Fallback for failures that should be made more specific when possible.

Implementations

impl ExchangeError

pub fn is_transient(&self) -> bool

Is this error transient (should retry)?

pub fn is_502(&self) -> bool

Is this a 502 (exchange halted)?

Trait Implementations

impl Clone for ExchangeError

fn clone(&self) -> ExchangeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExchangeError

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

Formats the value using the given formatter.

impl Display for ExchangeError

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

Formats the value using the given formatter.

impl Error for ExchangeError

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.
