Struct lib_xch::public::handler::Handler

pub struct Handler<'a, T> { /* fields omitted */ }

A handler which store the equation and other information

Methods

impl<'a, T: CheckedType + CheckedCalc> Handler<'a, T> where     ParseIntError: From<<T as Num>::FromStrRadixErr> + From<<T as FromStr>::Err>,

pub fn new(equ: &'a str) -> Self

Create a Handler by given equation

pub fn handle(self) -> Result<(ChemicalEquation, Vec<Vec<T>>), ErrorCases>

Parse and balance the equation. If it has been parsed, then just balance it.

If the equation can balance, function would return Ok((ChemicalEquation, Vec<Vec<T>>)) which contains the answer.

If not, it would return Err(ErrorCases) which contains the failure.

Panics

• A large number (bigger than usize::MAX) of formula may cause panic. Because it is using Vec.

And in the other failed situation, it'll return ErrorCases.

pub fn parse(&mut self) -> Result<(ChemicalEquation, Vec<Vec<T>>), ErrorCases>

Parse the equation
