Enum PartialError 

pub enum PartialError {
    Format {
        kind: PartialFormatErrorKind,
    },
    DatasetMismatch {
        expected: [u8; 32],
        actual: [u8; 32],

    PartitionOverlap {
        rank_a: u32,
        rank_b: u32,

    },
    RankCollision {
        rank_id: u32,
    },
}

Top-level error returned by the encode/decode and merge surface in this crate. Each variant maps 1:1 to one of the five Python exception classes (PartialFormatMismatch, PartialDatasetMismatch, PartialParamsMismatch, PartialPartitionOverlap, PartialRankCollision).

Variants

Format

Framing or structural check tripped. See PartialFormatErrorKind for which one.

Fields

kind: PartialFormatErrorKind

Sub-discriminator naming the specific check.

DatasetMismatch

Partial’s dataset_hash does not match the receiving rank’s live dataset. Sampler / config bug; refusing protects the merge from silently producing un-reproducible numbers.

Fields

expected: [u8; 32]

Receiving rank’s dataset_hash.

actual: [u8; 32]

Partial’s declared dataset_hash.

ParamsMismatch

Partial’s params_hash does not match the receiving rank’s. Means params (max_dets / iou_thresholds / use_cats / …) diverged.

Fields

expected: [u8; 32]

Receiving rank’s params_hash.

actual: [u8; 32]

Partial’s declared params_hash.

PartitionOverlap

Two partials cover the same image_id — the disjoint-partition rule is violated. Names both rank ids and the colliding image so the user can fix their DistributedSampler.

Fields

rank_a: u32

Lower rank id (min(a, b)) — sorted for determinism.

rank_b: u32

Higher rank id.

image_id: i64

Image id that appeared in both partials’ seen_images.

RankCollision

Two strict-mode partials declare the same rank_id. Strict merge requires distinct ids so the cross-rank tiebreak gives a total order. Corrected mode tolerates collisions.

Fields

rank_id: u32

The duplicated rank id.

Trait Implementations

impl Clone for PartialError

fn clone(&self) -> PartialError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PartialError

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

Formats the value using the given formatter.

impl Display for PartialError

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

Formats the value using the given formatter.

impl Error for PartialError

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 PartialEq for PartialError

fn eq(&self, other: &PartialError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
