Struct Problem 

#[non_exhaustive]
pub struct Problem {
    pub factors: Vec<Factor>,
    pub groups: Option<Vec<Group>>,
}

The declarative input-space description for an SA campaign.

factors + optional groups. Future fields (correlation, output) land via follow-on PRs (each has its own design questions). Problem is #[non_exhaustive] — adding those fields is non-breaking.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

factors: Vec<Factor>

groups: Option<Vec<Group>>

Factor groups for grouped SA. None = ungrouped (each factor independent).

Implementations

impl Problem

pub fn dim(&self) -> usize

Number of factors.

pub fn factors(&self) -> &[Factor]

Read-only view of factors.

pub fn content_hash(&self) -> [u8; 32]

SHA-256 over the canonical-JSON serialization. Stable across calls; content-equivalent Problems hash equally.

Panics

Never. serde_json::to_vec on a Problem cannot fail — every field is plain data.

Trait Implementations

impl Clone for Problem

fn clone(&self) -> Problem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Problem

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Problem

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Problem

fn eq(&self, other: &Problem) -> 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.

impl Serialize for Problem

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
