Enum ProviderError 

pub enum ProviderError {
    NotFound {
        key: String,
    },
    Backend {
        detail: String,
    },
}

Outcome of a ContentProvider lookup.

Kept distinct from Result<Option<…>> because adapters frequently want to distinguish a hard error (KV unreachable) from a benign miss (key not in store).

Examples

use ssg_core::ProviderError;

let err = ProviderError::NotFound { key: "foo.md".into() };
assert!(err.to_string().contains("not found"));
assert!(err.to_string().contains("foo.md"));

Variants

NotFound

Key was not present in the underlying store.

Fields

key: String

The key that was requested.

Backend

Backend I/O failure (network, disk, decode).

Fields

detail: String

Human-readable detail, suitable for logs.

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, f: &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.
