Person_struct_parser(PSP) is a parsing library for parsing a String into a person object.

• PSP has structure Person(person_struct_parser::person_module::Person) for containing the information about a person(name,age,city)

pub struct Person {
        pub name: String,
        pub age: u32,
        pub city: String,
    }

• Function person_struct_parser::person_module::parse is implemented for Person, it's main method for parsing String into the Person object:

pub fn parse(string: &str) -> anyhow::Result<Person>

• std::fmt::Display is implemented for Person
• There is function person_struct_parser::person_module::normalize implemented for Person to reduce object data to normal form:

pub fn normalize(&mut self) -> &mut Self

• The grammar for parsing is placed in grammar.pest file in src folder.

alpha = { 'a'..'z' | 'A'..'Z' }
digit = { '0'..'9' }

name = {(alpha)+}
age = {(digit)+}
city = {(alpha)+}
person = {name~age~city}
