Enum b2_client::error::Error

pub enum Error<E> where
    E: Debug + Display,  {
    Client(E),
    IO(Error),
    B2(B2Error),
    Format(Error),
    Unauthorized(Capability),
    Validation(ValidationError),
    MissingAuthorization,
    NoRequest,
}

Errors related to making B2 API calls.

Variants

Client(E)

An error from the underlying HTTP client.

IO(Error)

An I/O error from the local filesystem.

B2(B2Error)

An error from the Backblaze B2 API.

Format(Error)

An error deserializing the HTTP client’s response.

Unauthorized(Capability)

The Authorization lacks a required capability to perform a task. The provided capability is required.

This error is typically used when the B2 API returns null rather than returning an error or to return what we know will be an authorization error prior to sending a request to the API.

Validation(ValidationError)

An error validating data prior to making a Backblaze B2 API call.

MissingAuthorization

Attempted to send a request without a valid Authorization.

NoRequest

Attempted to send a non-existent request.

Trait Implementations

impl<E> Error for Error<E> where
    E: Debug + Display, 

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
