Enum PipelineError 

pub enum PipelineError {
    Unreadable {
        path: PathBuf,
        source: Error,
    },
    Uninspectable {
        name: String,
        message: String,
    },
    Resolution(CatalogError),
    SeamMismatch {
        producer: String,
        produced: String,
        consumer: String,
        expected: String,
    },
    Empty,
}

Why a pipeline was rejected.

Variants

Unreadable

A block could not be read from disk.

Fields

path: PathBuf

The block that could not be read.

source: Error

The underlying I/O failure.

Uninspectable

A stage could not be inspected: a directory instead of an artifact, unrecognized magic bytes, a wasm module that failed to load, or a bundle whose cached signature string doesn’t parse.

Fields

name: String

The stage’s display name.

message: String

What went wrong.

Resolution(CatalogError)

Resolving a pipeline entry through the catalog failed.

SeamMismatch

Two adjacent blocks do not fit.

Fields

producer: String

The block producing the value.

produced: String

What it produces.

consumer: String

The block receiving it.

expected: String

What it needs.

Empty

The pipeline had no blocks.

Trait Implementations

impl Debug for PipelineError

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

Formats the value using the given formatter.

impl Display for PipelineError

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

Formats the value using the given formatter.

impl Error for PipelineError

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<CatalogError> for PipelineError

fn from(source: CatalogError) -> Self

Converts to this type from the input type.

impl From<PipelineError> for DagError

fn from(source: PipelineError) -> Self

Converts to this type from the input type.
