Struct ParameterSpace 

pub struct ParameterSpace { /* private fields */ }

A validated immutable fixed-and-swept parameter definition.

Cloning this type clones only an Arc. Parsed source values, lookup indexes, Cartesian strides, explicit cases, and exact source bytes remain in one shared allocation.

Implementations

impl ParameterSpace

pub fn load( configuration_directory: impl Into<PathBuf>, ) -> Result<Self, ConfigurationError>

Loads fixed.json and sweep.json from configuration_directory.

The directory is the config/ directory itself. The later ProjectConfig facade accepts a project root and applies that standard suffix automatically.

Errors

Returns contextual IO or JSON errors, duplicate-key and document-shape errors, fixed/sweep collisions, empty sweep definitions, or checked task count overflow. Neither source file is modified.

pub fn configuration_directory(&self) -> &Path

Returns the configuration directory exactly as supplied at load time.

pub fn fixed_source_json(&self) -> &[u8]

Borrows the validated original bytes of fixed.json unchanged.

These bytes include the source document’s original whitespace, key presentation order, and number spelling.

pub fn sweep_source_json(&self) -> &[u8]

Borrows the validated original bytes of sweep.json unchanged.

pub fn fixed_parameter_count(&self) -> usize

Returns the number of names supplied by fixed.json.

pub fn sweep_parameter_count(&self) -> usize

Returns the number of names supplied by one resolved sweep selection.

pub fn parameter_count(&self) -> usize

Returns the number of entries in every resolved task dictionary.

pub fn task_count(&self) -> u64

Returns the exact checked number of deterministic task combinations.

pub fn contains_parameter(&self, key: &str) -> bool

Reports whether either the fixed table or sweep definition declares an exact parameter key.

pub fn fixed_keys(&self) -> impl ExactSizeIterator<Item = &str>

Iterates fixed parameter names in their JSON declaration order.

pub fn sweep_keys(&self) -> impl ExactSizeIterator<Item = &str>

Iterates swept parameter names in declared axis or first-case order.

pub fn task(&self, ordinal: u64) -> Result<TaskParameters, ConfigurationError>

Resolves one zero-based deterministic task ordinal.

The returned dictionary shares this space’s allocation and computes selected values lazily during lookup. No parameter value is cloned.

pub fn tasks(&self) -> TaskParametersIter

Iterates every resolved task in increasing deterministic ordinal order.

Iterator items cannot fail because the range is constructed from the already validated task count.

Trait Implementations
