Enum ProviderError 

#[non_exhaustive]
pub enum ProviderError {
    Transport {
        context: String,
        cause: ErrorCause,
    },
    Provider {
        context: String,
        message: String,
        status: Option<u16>,
    },
    Decode {
        context: String,

    Unsupported {

}

Failure of a context-provider operation.

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.

Transport

The network/HTTP layer failed before a usable response arrived.

Fields

context: String

What the adapter was doing, e.g. "fetching METARs".

cause: ErrorCause

Underlying transport error.

Provider

The provider answered, but with an error (HTTP status or in-band fault).

Fields

context: String

What the adapter was doing.

message: String

Provider-supplied error message.

status: Option<u16>

HTTP status code, when the error surfaced at the HTTP layer.

Decode

The response arrived but could not be decoded.

Fields

context: String

What the adapter was doing.

cause: ErrorCause

Underlying decode error.

Unsupported

This source cannot serve the requested shape.

Fields

reason: String

Why the request cannot be served, e.g. an crate::Area variant the provider has no equivalent for.

Trait Implementations

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl Display for ProviderError

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

Formats the value using the given formatter.

impl Error for ProviderError

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.
