Enum UnknownSourceError 

pub enum UnknownSourceError {
    Unknown(String),
    RequiresPath(&'static str),
    RequiresTransport(&'static str),
    FeatureDisabled(&'static str, &'static str),
}

Reasons an identifier-based chain could not be built.

Variants

Unknown(String)

The identifier didn’t match any built-in source.

RequiresPath(&'static str)

The identifier names a source that requires a caller-supplied path (e.g. file-override, kubernetes-downward-api). Build it manually with the typed constructor and chain via .push(...).

RequiresTransport(&'static str)

The identifier names a cloud source that needs an HTTP transport; use [resolver_from_ids_with_transport].

FeatureDisabled(&'static str, &'static str)

The identifier is valid but its crate feature is not enabled in this build.

Trait Implementations

impl Debug for UnknownSourceError

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

Formats the value using the given formatter.

impl Display for UnknownSourceError

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

Formats the value using the given formatter.

impl Error for UnknownSourceError

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.
