Enum Error 

#[non_exhaustive]
pub enum Error {
    Validation(ValidationError),
    Io {
        path: PathBuf,
        source: Error,
    },
    Limit {
        kind: LimitKind,
        observed: u64,
        limit: u64,
    },
    Provider(ProviderError),
    Export(ExportError),
}

Top-level error returned by every public tfparser_core API.

Per the spec’s stability contract ([10-data-model.md § Versioning], the variants below are #[non_exhaustive] so future phases can add error kinds without a major bump. Match arms should always include a catch-all.

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.

Validation(ValidationError)

A validated newtype rejected its input (length, charset, or shape invariant). The accompanying ValidationError names the field and the rule.

Io

I/O error reading or writing a path.

Fields

path: PathBuf

Path that triggered the error.

source: Error

Underlying I/O error.

Limit

A configured resource limit was exceeded. The accompanying crate::diagnostic::LimitKind identifies which one.

Fields

kind: LimitKind

Which limit category fired.

observed: u64

Observed value.

limit: u64

Configured limit.

Provider(ProviderError)

Provider resolver (Phase 7) raised a fatal error.

Export(ExportError)

Parquet exporter (Phase 3+) raised a fatal error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<ExportError> for Error

fn from(source: ExportError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for Error

fn from(source: ProviderError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for Error

fn from(source: ValidationError) -> Self

Converts to this type from the input type.
