Struct ClassificationState 

pub struct ClassificationState {
    pub identifier: SubstanceIdentifier,
    pub is_mixture: Option<bool>,
    pub component_count: Option<usize>,
    pub components: Vec<PartialComponent>,
    pub current_component_index: usize,
    pub physical_form: Option<PhysicalForm>,
    pub purity_pct: Option<f64>,
    pub organic_inorganic: Option<OrganicInorganic>,
    pub chapter_hint: Option<String>,
    pub intended_use: Option<IntendedUse>,
    pub detected_functional_groups: Vec<String>,
    pub is_complete: bool,
}

Classification state accumulated across session Q&A rounds.

Each field starts as None and is filled in as the user answers questions. The pipeline reads this state (via to_product_description) when the session is complete.

Fields

identifier: SubstanceIdentifier

Identifier entered by the user in the first question.

is_mixture: Option<bool>

Whether the product is a mixture. None = not yet answered.

component_count: Option<usize>

Number of components (set when is_mixture = true).

components: Vec<PartialComponent>

Components collected so far (built up one at a time).

current_component_index: usize

Index of the component currently being entered.

physical_form: Option<PhysicalForm>

purity_pct: Option<f64>

organic_inorganic: Option<OrganicInorganic>

Organic / inorganic classification. None = not yet answered.

chapter_hint: Option<String>

HS chapter hint narrowed down by the rule engine (two-digit string, e.g. "28").

intended_use: Option<IntendedUse>

detected_functional_groups: Vec<String>

Functional group keys selected by the user (e.g. "carboxylic_acid").

is_complete: bool

Set to true when next_question() returns None.

Implementations

impl ClassificationState

pub fn has_identifier(&self) -> bool

Returns true if at least one identifier field has been set.

pub fn confidence_estimate(&self) -> f32

Rough confidence estimate based on how many fields are known.

Used to decide whether to emit SessionResult::RequiresLlm when all questions have been answered.

pub fn all_components_filled(&self) -> bool

Returns true if all expected mixture components have been entered.

Always returns true for non-mixture products.

pub fn current_component_has_identifier(&self) -> bool

Returns true if the current mixture component has an identifier.

pub fn current_component_has_fraction(&self) -> bool

Returns true if the current mixture component has a weight fraction.

Trait Implementations

impl Clone for ClassificationState

fn clone(&self) -> ClassificationState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClassificationState

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

Formats the value using the given formatter.

impl Default for ClassificationState

fn default() -> ClassificationState

Returns the “default value” for a type.
