Struct Sentiment 

pub struct Sentiment {
    pub positive_hits: u32,
    pub negative_hits: u32,
    pub tokens: u32,
}

The polarity result of scoring a piece of text.

All fields are derived from simple case-insensitive whole-word matching against POSITIVE_WORDS and NEGATIVE_WORDS.

Fields

positive_hits: u32

Number of positive lexicon words matched.

negative_hits: u32

Number of negative lexicon words matched.

tokens: u32

Total tokens the lexicons were matched against (word count).

Implementations

impl Sentiment

pub fn net(&self) -> i64

Net polarity: positive_hits - negative_hits.

Positive when the text leans positive, negative when it leans negative, zero when balanced (or empty).

pub fn comparison(&self) -> f64

Comparison score in -1.0..=1.0: (positive - negative) / (positive + negative).

Returns 0.0 when no polarity words were found.

pub fn positive_share(&self) -> f64

Proportion of polarity-bearing tokens that are positive, in 0.0..=1.0.

Returns 0.0 when no polarity words were found.

pub fn label(&self) -> &'static str

Coarse label for the overall polarity.

Trait Implementations

impl Clone for Sentiment

fn clone(&self) -> Sentiment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sentiment

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

Formats the value using the given formatter.

impl Eq for Sentiment

impl PartialEq for Sentiment

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