PhoneNumberParser
This is a Rust library for parsing and validating Ukrainian phone numbers in the format "+380XXXXXXXXX." It uses the Pest library for parsing.
Parsing Process
The PhoneNumberParser library is designed to parse and validate Ukrainian phone numbers. It defines a grammar in the grammar.pest
file, which specifies the format of a valid phone number. The parser then uses this grammar to validate phone numbers provided as input strings.
The parsing process involves the following steps:
-
The input string is processed by the PhoneNumberParser, which checks if it matches the grammar rules.
-
The parser validates that the phone number starts with "+380" and is followed by digits
Usage
You can use the PhoneNumberParser in your Rust project to validate Ukrainian phone numbers. The library provides a is_valid_phone_number
function, which returns true
for valid phone numbers and false
for invalid ones.
use phone_number_parser::is_valid_phone_number;
fn main() {
let phone_numbers = vec!["+380992121211", "+38099232323", "123456789", "+380992121a11"];
for phone_number in phone_numbers {
if is_valid_phone_number(phone_number) {
println!("Valid phone number: {}", phone_number);
} else {
println!("Invalid phone number: {}", phone_number);
}
}
}
You can check different tests in this code block:
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_valid_phone_numbers() -> anyhow::Result<()> {
let pair = PhoneNumberParser::parse(Rule::phoneNumber, "+380992121211")?.next().ok_or_else(|| anyhow!("no pair"))?;
assert_eq!( pair.as_span().start(), 0 );
assert_eq!( pair.as_span().end(), 13 );
Ok(())
}
#[test]
fn test_valid_phone_numbers_fail() -> anyhow::Result<()> {
let pair = PhoneNumberParser::parse(Rule::phoneNumber, "380992121211");
assert!( pair.is_err() );
Ok(())
}
#[test]
fn test_valid_phone_numbers_fail_lenght() -> anyhow::Result<()> {
let pair = PhoneNumberParser::parse(Rule::phoneNumber, "+380992121")?.next().ok_or_else(|| anyhow!("no pair"))?;
assert_eq!( pair.as_span().start(), 0 );
assert_eq!( pair.as_span().end(), 13, "Must be +38 and 10 digits in lenght!" );
Ok(())
}
}
