Struct Situation 

Source 
pub struct Situation {
    pub tokens: Vec<String>,
    pub display: Vec<String>,
    pub numbers: Vec<(String, f64)>,
    pub beliefs: Vec<(String, f32)>,
}
Expand description

One projected record: the tokens it asserts (for set-algebra), the cells to show for it, and any numeric fields it carries (for (num <field> <op> <value>) range predicates — e.g. a CSV numeric column or a canonicalised quantity span like qty-length = 70 m).

Fields§

§tokens: Vec<String>§display: Vec<String>§numbers: Vec<(String, f64)>§beliefs: Vec<(String, f32)>

Infon polarity per token (paper §1.2): (token, i) where i ∈ {-1, -0.5, +0.5, +1}. Only tokens whose polarity differs from the default +1 need an entry; the rest are asserted-positive. Populated from the tagger’s epistemic head and consumed by InfonIndex::add_infon_polar.

Implementations§

Source§

impl Situation

Source

pub fn new(tokens: Vec<String>, display: Vec<String>) -> Situation
