Errors produced by the MAE pretraining patchify / masking functions (crate::mae, ADR-152 §2.3).

Variants

WindowShapeMismatch

The flat window buffer does not match the declared time × subc shape.

Fields

time: usize

Declared time dimension.

subc: usize

Declared subcarrier dimension.

expected: usize

Expected buffer length (time * subc).

actual: usize

Actual buffer length.

PatchExceedsWindow

A patch dimension is larger than the window along that axis.

Fields

axis: &'static str

Axis name ("time" or "subcarrier").

patch: usize

Patch extent along the axis.

window: usize

Window extent along the axis.

NotDivisible

The window is not an exact multiple of the patch extent along an axis.

Patchification never silently truncates; crop the window to crop (the largest divisible extent) or change the patch size.

Fields

axis: &'static str

Axis name ("time" or "subcarrier").

window: usize

Window extent along the axis.

patch: usize

Patch extent along the axis.

remainder: usize

window % patch.

crop: usize

Largest divisible extent (window - remainder).

InvalidMaskRatio

The mask ratio is not a finite value strictly inside (0, 1) — the same rule as MaePretrainConfig::validate. A NaN ratio must never silently mask zero patches, and ratios ≤ 0 / ≥ 1 degenerate to all-visible / all-masked grids.

Fields

ratio: f64

The offending ratio.

NonFiniteValue

A NaN or ±inf CSI value was found; corrupted input must be cleaned upstream, never masked over.

Fields

row: usize

Time index of the offending value.

col: usize

Subcarrier index of the offending value.

value: f32

The non-finite value itself.

Trait Implementations

impl Debug for MaeError

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

Formats the value using the given formatter.

impl Display for MaeError

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

Formats the value using the given formatter.

impl Error for MaeError

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<MaeError> for TrainError

fn from(source: MaeError) -> Self

Converts to this type from the input type.
