Enum ConnectivityError 

#[non_exhaustive]
pub enum ConnectivityError {
    ExchangeOffline(ExchangeId),
    Timeout,
    Socket(String),
}

Represents all connectivity-centric errors.

Connectivity errors are generally intermittent / non-deterministic (eg/ Timeout). All variants are transient — retry with exponential backoff (typically 1-30s).

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.

ExchangeOffline(ExchangeId)

Exchange is offline, likely due to scheduled maintenance.

Transient — retry with backoff. Maintenance windows typically last minutes to hours; consider longer backoff intervals (30s-5min) to avoid log spam.

Timeout

Request timed out before a response was received.

Transient — retry with backoff. May indicate network congestion, server overload, or an overly aggressive timeout. Consider increasing timeout on subsequent attempts.

Socket(String)

Network-level socket error (connection refused, reset, DNS failure, etc.).

Transient — retry with backoff. If persistent, may indicate firewall issues, incorrect endpoint configuration, or prolonged server outage.

Implementations

impl ConnectivityError

pub fn is_transient(&self) -> bool

Returns true if this connectivity error is transient.

All connectivity errors are considered transient — they represent temporary network or server conditions that may resolve with retry.

impl Eq for ConnectivityError

impl Error for ConnectivityError

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<AssetKey, InstrumentKey> From<ConnectivityError> for ClientError<AssetKey, InstrumentKey>

fn from(source: ConnectivityError) -> Self

Converts to this type from the input type.

impl<AssetKey, InstrumentKey> From<ConnectivityError> for OrderError<AssetKey, InstrumentKey>

fn from(source: ConnectivityError) -> Self

Converts to this type from the input type.

impl From<SocketError> for ConnectivityError

fn from(value: SocketError) -> Self

Converts to this type from the input type.

impl Hash for ConnectivityError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ConnectivityError

fn cmp(&self, other: &ConnectivityError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,
