Enum LoadError 

pub enum LoadError {
    NoSources,
    MissingModules(Vec<String>),
    DiagnosticThreshold,
    Source(Box<dyn Error + Send + Sync>),
    Io(Error),
}

Errors returned by Loader::load and the free function load.

All variants carry enough context for callers to present useful error messages. The Display implementation produces human-readable text for each case.

Variants

NoSources

No Sources were configured on the Loader.

MissingModules(Vec<String>)

One or more explicitly requested modules were not found after resolution.

The contained Vec lists the missing module names.

DiagnosticThreshold

A diagnostic exceeded the configured fail-at severity threshold.

See DiagnosticConfig for threshold configuration.

Source(Box<dyn Error + Send + Sync>)

A Source implementation returned a custom error.

Use LoadError::from_source to construct this variant from an arbitrary error type.

Io(Error)

An I/O error occurred while reading MIB files from disk.

Implementations

impl LoadError

pub fn from_source(err: impl Error + Send + Sync + 'static) -> Self

Wrap an arbitrary error as a LoadError::Source.

Useful for custom Source implementations that need to return domain-specific errors through the loading pipeline.

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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 From<Error> for LoadError

fn from(source: Error) -> Self

Converts to this type from the input type.
