Struct pragmatic_segmenter::Segmenter

pub struct Segmenter { /* private fields */ }

Segmenter type. It stores the compilation results of regular expressions used internally by pragmatic-segmenter in memory.

use pragmatic_segmenter::Segmenter;

let segmenter = Segmenter::new()?;
let result: Vec<_> = segmenter.segment("Hi Mr. Kim. Let's meet at 3 P.M.").collect();
assert_eq!(result, vec!["Hi Mr. Kim. ", "Let's meet at 3 P.M."]);

Implementations

impl Segmenter

pub fn new() -> Result<Self, Box<dyn Error>>

Create a new Segmenter instance. The regular expressions used internally by pragmatic-segmenter are compiled here.

use pragmatic_segmenter::Segmenter;

let segmenter = Segmenter::new()?;

pub fn segment<'a>( &'a self, original_input: &'a str ) -> impl Iterator<Item = &'a str>

Separate sentences from given input. Although it is a function that returns an Iterator, not all processing is done by streaming. After pre-processing the entire input once, processing is performed for each sentence by streaming.

use pragmatic_segmenter::Segmenter;

let segmenter = Segmenter::new()?;
let mut iter = segmenter.segment("Hi Mr. Kim. Let's meet at 3 P.M.");

assert_eq!(iter.next(), Some("Hi Mr. Kim. "));
assert_eq!(iter.next(), Some("Let's meet at 3 P.M."));
assert_eq!(iter.next(), None);
