Struct NgramsFile 

pub struct NgramsFile {
    pub ngrams: HashMap<Bytes, usize>,
    pub ftype: FileType,
    pub n: usize,
}

N-grams as read from a file

Fields

ngrams: HashMap<Bytes, usize>

N-grams and their index position

ftype: FileType

File type represented by the n-grams

n: usize

Convenience: keep track of the size of the n-grams (value of n)

Implementations

impl NgramsFile

pub fn load<P: AsRef<Path>>(ngrams_file: P) -> Result<Self>

Load the n-grams from a plain text file

Errors

An error results if:

• The file cannot be read
• The file type is not specified
• The n-grams aren’t hexidecimal
• The n-grams are different sizes

pub fn into_vec(self) -> Vec<Bytes>

Convert the n-gram map into a vector, preserving their order

Trait Implementations

impl Clone for NgramsFile

fn clone(&self) -> NgramsFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.
