}

An error that can occur while working with Databento’s API.

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.

BadArgument

An invalid argument was passed to a function.

Fields

param_name: &'static str

The name of the parameter to which the bad argument was passed.

desc: String

The description of why the argument was invalid.

Io(Error)

Http(Error)

Available on crate feature historical only.

An HTTP error.

Json(Error)

Available on crate feature historical only.

An error related to JSON decoding.

Utf8(Utf8Error)

Available on crate feature historical only.

An error related to JSON decoding.

Api(ApiError)

Available on crate feature historical only.

An error from the Databento API.

Internal(String)

An error internal to the client.

Dbn(Error)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
