Shard directories that cannot be merged.

Variants

NoInputs

A merge with no input directories.

Manifest(ManifestError)

A manifest that cannot be read.

Table(ReadError)

A table that cannot be read back.

BadShard

A manifest in dir whose shard no plan can have.

Fields

dir: PathBuf

Path of the input directory.

NoTables

Inputs with no runs.csv or series.csv header between them.

PlanDiffers

Input dir holds a different plan, model schema or replicate count than input first.

Fields

dir: PathBuf

Path of the input directory that differs.

first: PathBuf

Path of the input directory with the lowest shard index.

ShardCountDiffers

Input dir splits the plan into a different number of shards than input first.

Fields

dir: PathBuf

Path of the input directory that differs.

first: PathBuf

Path of the input directory with the lowest shard index.

SameShard

Inputs first and second both hold shard.

Fields

shard: Shard

Shard both inputs record.

first: PathBuf

Path of the input directory given earlier.

second: PathBuf

Path of the input directory given later.

ColumnsDiffer

file of input dir has different columns from the other inputs.

Fields

dir: PathBuf

Path of the input directory that differs.

file: &'static str

File name of the table, runs.csv or series.csv.

RunIdDiffers

Run run_id of input dir, written as replicate rep of config config_id under a different id than the one that the manifest’s replicate count implies.

Fields

dir: PathBuf

Path of the input directory.

run_id: u64

Run id as written in runs.csv.

config_id: u64

Config id as written in runs.csv.

rep: u64

Replicate index as written in runs.csv, counting from 0.

OutsideShard

Run run_id of input dir, outside its shard or past the plan’s runs.

Fields

dir: PathBuf

Path of the input directory.

run_id: u64

Run id as written in runs.csv.

DuplicateRun

Run run_id, listed twice in runs.csv of input dir.

Fields

dir: PathBuf

Path of the input directory.

run_id: u64

Run id as written in runs.csv.

Output(OutputError)

The merged directory cannot be written.

NotASweep

Input dir holds a search. A search runs whole and has no shards.

Fields

dir: PathBuf

Path of the input directory.

Trait Implementations

impl Debug for MergeError

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

Formats the value using the given formatter.

impl Display for MergeError

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

Formats the value using the given formatter.

impl Error for MergeError

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.
