Enum GeneratorError 

#[non_exhaustive]
pub enum GeneratorError {
    FileRead {
        path: String,
        source: Error,
    },
}

Errors originating from value or log generators.

Currently contains FileRead for I/O failures when loading generator data from disk. This enum is designed for extensibility — future variants may include InvalidData (malformed file contents), ParseFailed (unparseable numeric columns), or UnsupportedFormat as generator capabilities grow.

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.

FileRead

Failed to read a generator input file (CSV replay, log replay).

Preserves the original std::io::Error via the #[source] attribute so callers can inspect the error kind (e.g., ErrorKind::NotFound vs ErrorKind::PermissionDenied) programmatically.

Fields

path: String

The path that could not be read.

source: Error

The underlying I/O error.

Implementations

impl GeneratorError

pub fn source_io_kind(&self) -> Option<ErrorKind>

Returns the std::io::ErrorKind of the underlying I/O error, if this is a FileRead variant.

Convenience method that lets callers inspect the error kind without manually traversing the source() chain.

Trait Implementations

impl Debug for GeneratorError

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

Formats the value using the given formatter.

impl Display for GeneratorError

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

Formats the value using the given formatter.

impl Error for GeneratorError

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<GeneratorError> for SondaError

fn from(source: GeneratorError) -> Self

Converts to this type from the input type.
