Enum ParseError 

#[non_exhaustive]
pub enum ParseError {
    Parse(String),
    InvalidIdentifier {
        kind: &'static str,
        value: String,
        reason: String,
    },
    Internal(String),
    Io {
        path: PathBuf,
        source: Error,
    },
    NoBackend,
}

Errors returned by either backend.

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.

Parse(String)

Underlying Python parser rejected the source.

InvalidIdentifier

Recovered identifier failed Airflow-safe validation.

Fields

kind: &'static str

Identifier kind ("dag_id" / "task_id") — propagated as a static string so the caller can pattern-match without allocating.

value: String

The raw literal that failed validation.

reason: String

Reason from the validator.

Internal(String)

Internal invariant violated; should never reach a caller.

Io

I/O failure while loading a DAG file from disk.

Fields

path: PathBuf

Path that failed to read.

source: Error

Underlying OS error.

NoBackend

No backend feature was enabled at compile time.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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.
