Errors produced by fpm-rs public operations.

Variants

InvalidShape(String)

A supplied or derived array shape is empty, inconsistent, or unsupported.

InvalidParameter

A named scalar or option falls outside its accepted domain.

Fields

name: &'static str

Stable parameter name.

reason: String

Explanation of the rejected value or relationship.

InvalidModel(String)

A compiled image-plane model violates a model invariant.

InvalidMeasurements(String)

Measurements or their metadata are incompatible or invalid.

LengthMismatch

A flat two-dimensional buffer length does not match its (height, width) shape.

Fields

actual: usize

Number of supplied elements.

expected: usize

Number of elements required by shape.

shape: (usize, usize)

Requested (height, width) shape.

ArrayLengthMismatch

A flat buffer length does not match a general-dimensional shape.

Fields

actual: usize

Number of supplied elements.

expected: usize

Number of required elements.

shape: Vec<usize>

Requested axis lengths.

ShapeOverflow

Multiplying the dimensions of an array shape overflowed addressable storage.

Fields

shape: Vec<usize>

Axis lengths whose product overflowed.

NonStandardLayout

An ndarray input is not C-contiguous standard row-major storage.

Fields

context: &'static str

User-facing name of the offending value.

shape: Vec<usize>

Logical axis lengths.

strides: Vec<isize>

Element strides reported by ndarray.

NdarrayShape(ShapeError)

ndarray rejected a requested shape or storage layout.

FrameOutOfRange

A requested acquisition-frame index is outside 0..frames.

Fields

index: usize

Requested zero-based frame index.

frames: usize

Available frame count.

Numerical(String)

A numerical operation produced an invalid or unusable value.

Unsupported(String)

The requested operation is not implemented for the supplied input.

Dataset(String)

Dataset discovery, download, verification, or loading failed.

UnsupportedBundleVersion

A result or benchmark bundle uses an unsupported manifest version.

Fields

actual: u32

Version found in the manifest.

supported: u32

Version supported by this build.

InvalidManifest(String)

A bundle manifest is malformed or violates the bundle contract.

MissingArtifact

A manifest-declared bundle artifact is absent.

Fields

role: String

Stable artifact role from the manifest.

ArtifactHashMismatch

A bundle artifact’s bytes do not match its declared SHA-256 digest.

Fields

role: String

Stable artifact role from the manifest.

InvalidParquetSchema

A Parquet artifact does not have the schema required for its role.

Fields

role: String

Stable artifact role from the manifest.

reason: String

Description of the schema mismatch.

InconsistentRunId

Artifacts within one bundle disagree about the run identifier.

Fields

expected: String

Run identifier required by the bundle manifest.

actual: String

Run identifier found in an artifact.

InvalidArrayShape

A stored NPY array has a shape inconsistent with its artifact role.

Fields

role: String

Stable array role from the manifest.

reason: String

Description of the shape mismatch.

InvalidArrayDtype

A stored NPY array has the wrong element dtype for its role.

Fields

role: String

Stable array role from the manifest.

actual: String

Dtype encoded by the array file.

expected: String

Dtype required for the artifact role.

UnsupportedArtifactRole(String)

A bundle manifest names an artifact role unknown to this version.

InvalidRelativePath(String)

A bundle artifact path is absolute or escapes the bundle directory.

IncompleteBundle(String)

A temporary bundle workspace is missing required output before publication.

Polars(PolarsError)

An operation delegated to Polars failed.

Io(Error)

A filesystem or stream operation failed.

Csv(Error)

Reading or writing CSV data failed.

Image(ImageError)

Decoding or encoding a general image failed.

Tiff(TiffError)

Reading a TIFF stack failed.

Serialization(Error)

JSON serialization or deserialization failed.

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
