A spec file that cannot be read or turned into a sweep spec.

Variants

Read

Reading the file at path failed.

Fields

path: PathBuf

Path of the spec file, or of a design table that it refers to, joined to the spec file’s directory.

source: Error

Error from reading the file, of kind InvalidData for text that is not UTF-8.

TablePath

Table path path of block block, absolute or holding a component other than a name, such as ...

Fields

block: usize

Index of the block, counting from 0.

path: PathBuf

Table path as written in the block’s file key.

Parse

Text that is not a spec file.

Fields

source: Box<Error>

Error from the TOML parser.

Json

JSON that is not a spec file.

Fields

source: Error

Error from the JSON deserializer.

FactorTarget

A factor of block block with none or both of param and action.

Fields

block: usize

Index of the block, counting from 0.

FactorLevels

Factor of block block on the parameter or action target_name, with none or several of values, range and levels.

Fields

block: usize

Index of the block, counting from 0.

target_name: String

Parameter id or action name the factor targets.

Design

Block block, whose keys do not fit its design.

Fields

block: usize

Index of the block, counting from 0.

reason: &'static str

Message that identifies the key at fault, such as samples applies to a random or lhs design.

Reducer(ReducerError)

A reducer kind that cannot be read.

Stop(StopError)

A stop condition that cannot be read.

Timeout

A timeout of seconds that is negative, not a number or too long for a Duration.

Fields

seconds: f64

Value of timeout_s in seconds, as written in the spec.

Search

A [search] table whose keys do not fit its algorithm or the rest of the spec.

Fields

reason: &'static str

Message that identifies the key at fault, such as [search.pse] applies to a pse search.

SearchFactorTarget

A factor of the search space with none or both of param and action.

SearchFactorLevels

A factor of the search space on the parameter or action target_name, with none or several of values, range and levels.

Fields

target_name: String

Parameter id or action name the factor targets.

Write

A spec that cannot be written as TOML.

Fields

source: Error

Error from the TOML serializer.

Trait Implementations

impl Debug for SpecFileError

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

Formats the value using the given formatter.

impl Display for SpecFileError

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

Formats the value using the given formatter.

impl Error for SpecFileError

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.
