Struct ChemicalFormula 

pub struct ChemicalFormula { /* private fields */ }

A chemical formula with a main part and optional hydrate parts.

Implementations

impl ChemicalFormula

pub fn new(main_part: FormulaPart, hydrate_parts: Vec<HydratePart>) -> Self

Creates a chemical formula from a main part and hydrate parts.

pub fn parse(input: &str) -> Result<Self, FormulaParseError>

Parses a chemical formula string.

Errors

Returns FormulaParseError when the input is empty or does not match the supported lightweight formula grammar.

pub const fn main_part(&self) -> &FormulaPart

Returns the main formula part.

pub fn hydrate_parts(&self) -> &[HydratePart]

Returns hydrate parts after the main formula part.

pub fn element_counts(&self) -> BTreeMap<String, u64>

Returns expanded element counts for the full formula.

Trait Implementations

impl Clone for ChemicalFormula

fn clone(&self) -> ChemicalFormula

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChemicalFormula

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ChemicalFormula

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for ChemicalFormula

type Err = FormulaParseError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ChemicalFormula

fn eq(&self, other: &ChemicalFormula) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
