Enum Error 

pub enum Error {
    ParseFailed {
        what: String,
        detail: String,
    },
    UnsupportedSource {
        what: String,
    },

    Extractor(String),
    Sidecar {
        tool: String,

    },
    Other(String),
}

Errors produced by the ingest pipeline.

Variants

ParseFailed

Parsing the source bytes failed.

what names the parser ("markdown", "text") and detail carries an upstream message suitable for logging - not for end-user display.

Fields

what: String

Short identifier of the parser that failed.

detail: String

Human-readable detail (may include upstream error text).

UnsupportedSource

The supplied crate::SourceKind is not yet supported in this sub-wave (e.g. PDF or Conversation before Phase-B5b/B5e).

Fields

what: String

Which source / feature was requested.

IoError(Error)

I/O failure reading a source artifact.

Commit(String)

A downstream Transaction::add_node / add_edge returned an error during pipeline execution. The embedded string carries the upstream mnem_core::Error display text so we avoid a cross-crate re-export while still preserving detail for logs.

Extractor(String)

An crate::extract::Extractor or embedder raised an error the pipeline could not recover from.

Sidecar

An optional sidecar binary (docling / unstructured, feature-gated in Phase-B5e) was requested but is not available on PATH, or returned a non-zero exit status / malformed output.

The tool field names the sidecar ("docling", "unstructured-ingest"); detail carries the failure mode ("binary not found", upstream stderr, or parse error).

Fields

tool: String

Short identifier of the sidecar that failed.

detail: String

Human-readable detail (may include upstream stderr or parse error text).

Other(String)

Catch-all for internal invariants. Prefer a typed variant for anything a caller might branch on.

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
