Enum DataSourceError 

pub enum DataSourceError {
    ConnError(String),
    FetchError(String),
    SymbolNotFound(String),
    InvalidTimeRange(String),
    IoError(String),
    ParseError(String),
    RateLimited,
    NotSupported(String),
}

Error types for data source operations.

All fallible DataSource methods return this error type. Use is_recoverable to decide whether an automatic retry is appropriate.

Variants

ConnError(String)

Failed to connect to data source

FetchError(String)

Failed to fetch data

SymbolNotFound(String)

Symbol not found

InvalidTimeRange(String)

Invalid time range

IoError(String)

IO error (cannot be cloned, stores error message)

ParseError(String)

Parse error

RateLimited

Request was rate limited

NotSupported(String)

Feature not supported by this data source

Implementations

impl DataSourceError

pub fn is_recoverable(&self) -> bool

Check if this error is recoverable (can retry)

pub fn is_conn_error(&self) -> bool

Check if this error is a conn-related error

pub fn message(&self) -> &str

Get the error message

Trait Implementations

impl Clone for DataSourceError

fn clone(&self) -> DataSourceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataSourceError

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

Formats the value using the given formatter.

impl Display for DataSourceError

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

Formats the value using the given formatter.

impl Error for DataSourceError

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<Error> for DataSourceError

fn from(err: Error) -> Self

Converts to this type from the input type.
