Implementations§

Source§

impl PatternDefinition

Source

pub fn new() -> PatternDefinition

Constructs a new PatternDefinition

§Example
extern crate test_data_generation;

use test_data_generation::engine::PatternDefinition;

fn main() {
	let pttrn_def = PatternDefinition::new();
}
Source

pub fn analyze(&mut self, entity: &str) -> (String, Vec<Fact>)

This function converts an entity (&str) into a tuplet (String, Vec)

§Arguments
  • entity: String - The textual str of the value to analyze.
§Example
extern crate test_data_generation;

use test_data_generation::engine::PatternDefinition;

fn main() {
	let mut pttrn_def = PatternDefinition::new();
    //async {
        let rslt = pttrn_def.analyze("Hello World");
        assert_eq!(rslt.0, "CvccvSCvccc");
    //}
}
Source

pub fn factualize(&mut self, entity: &str, idx: u32) -> Fact

This function converts a char in an entity (&str) based on the index specified into a Fact

§Arguments
  • entity: String - The textual str of the value to analyze.
  • idx: u32 - The index that specifies the position of the char in the entity to convert to a Fact.
§Example
extern crate test_data_generation;

use test_data_generation::engine::PatternDefinition;

fn main() {
	let mut pttrn_def = PatternDefinition::new();
	let fact = pttrn_def.factualize("Word",0);
    // will return a Fact that represents the char `W`
}
Source

pub fn get(&self, key: &str) -> char

This function returns a pattern symbol that represents the type of character

§Example
extern crate test_data_generation;

use test_data_generation::engine::PatternDefinition;

fn main() {
	let pttrn_def = PatternDefinition::new();
    println!("Upper case vowel symbol: {:?}", pttrn_def.get(&"VowelUpper".to_string()));
}
Source

pub fn symbolize_char(&self, c: char) -> char

This function converts a char into a pattern symbol

§Example
extern crate test_data_generation;

use test_data_generation::engine::PatternDefinition;

fn main() {
	let pttrn_def = PatternDefinition::new();
	println!("The pattern symbol for 'A' is {:?}", pttrn_def.symbolize_char('A'));
    // The pattern symbol for 'A' is V
}
