Enum LeanBuiltCapabilityError 

pub enum LeanBuiltCapabilityError {
    MissingDylibSource,
    MissingManifestSource,
    EnvVarNotSet {
        env_var: String,
        kind: BuiltCapabilityArtifact,
    },
}

Errors returned when resolving a LeanBuiltCapability descriptor.

Variants

MissingDylibSource

The descriptor has no dylib path and no dylib environment variable.

MissingManifestSource

The descriptor has no manifest path and no manifest environment variable.

EnvVarNotSet

The configured environment variable is not set at runtime.

Fields

env_var: String

Name of the environment variable that was queried.

kind: BuiltCapabilityArtifact

Which artifact the environment variable was supposed to point at.

Trait Implementations

impl Clone for LeanBuiltCapabilityError

fn clone(&self) -> LeanBuiltCapabilityError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LeanBuiltCapabilityError

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

Formats the value using the given formatter.

impl Display for LeanBuiltCapabilityError

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

Formats the value using the given formatter.

impl Error for LeanBuiltCapabilityError

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.

impl PartialEq for LeanBuiltCapabilityError

fn eq(&self, other: &LeanBuiltCapabilityError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
