    StrictSymbolsRejected {

}

Unified error type for the borsa workspace.

This wraps capability mismatches, argument validation errors, provider-tagged failures, not-found conditions, and an aggregate for multi-provider attempts.

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.

Unsupported

The requested capability is not implemented by the target connector.

Fields

capability: String

A capability string describing what was requested (e.g. “history/crypto”).

Data(String)

Issues with the returned or expected data (missing fields, etc.).

InvalidArg(String)

Invalid input argument.

Connector

An individual connector returned an error.

Fields

connector: String

Connector name that failed.

msg: String

Human-readable error message.

Other(String)

Unknown/opaque error.

NotFound

A resource or symbol could not be found.

Fields

what: String

Description of missing resource, e.g. “quote for AAPL”.

AllProvidersFailed(Vec<BorsaError>)

All selected providers failed; contains the individual failures.

ProviderTimeout

An individual provider call exceeded the configured timeout.

Fields

connector: String

Connector name that timed out.

capability: String

Capability label (e.g. “history”, “search”, “quote”).

RequestTimeout

The overall request exceeded the configured deadline.

Fields

capability: String

Capability label for which the request timed out.

AllProvidersTimedOut

All attempted providers timed out for the requested capability.

Fields

capability: String

Capability label that timed out across all providers.

StrictSymbolsRejected

Strict routing policy rejected one or more requested symbols for streaming.

Fields

rejected: Vec<String>

List of symbol strings that were excluded by strict routing rules.

Implementations

impl BorsaError

pub fn unsupported(cap: impl Into<String>) -> Self

Helper: build an Unsupported error for a capability string.

pub fn connector(connector: impl Into<String>, msg: impl Into<String>) -> Self

Helper: build a Connector error with the connector name and message.

pub fn not_found(what: impl Into<String>) -> Self

Helper: build a NotFound error for a description of the missing resource.

pub fn provider_timeout( connector: impl Into<String>, capability: impl Into<String>, ) -> Self

Helper: build a ProviderTimeout error.

pub fn request_timeout(capability: impl Into<String>) -> Self

Helper: build a RequestTimeout error.

pub fn is_actionable(&self) -> bool

Returns true if this error should be surfaced to users as actionable.

Non-actionable errors are those indicating capability absence or a benign not-found condition. Aggregates are classified based on their contents.

pub fn flatten(self) -> Vec<Self>

Flatten nested AllProvidersFailed structures into a plain vector.

This preserves other error variants as-is and unwraps recursively.

Trait Implementations

impl Clone for BorsaError

fn clone(&self) -> BorsaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BorsaError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BorsaError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BorsaError

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

Formats the value using the given formatter.

impl Error for BorsaError

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<DomainError> for BorsaError

fn from(e: DomainError) -> Self

Converts to this type from the input type.

impl From<Error> for BorsaError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<MarketError> for BorsaError

fn from(e: MarketError) -> Self

Converts to this type from the input type.

impl From<MoneyError> for BorsaError

fn from(e: MoneyError) -> Self

Converts to this type from the input type.

impl From<PaftError> for BorsaError

fn from(e: PaftError) -> Self

Converts to this type from the input type.

impl PartialEq for BorsaError

fn eq(&self, other: &BorsaError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BorsaError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BorsaError

impl StructuralPartialEq for BorsaError
