Struct ElementMassContribution 

pub struct ElementMassContribution { /* private fields */ }

A per-element contribution to a formula molar mass.

Implementations

impl ElementMassContribution

pub fn new( symbol: &str, atomic_mass: f64, count: u32, ) -> Result<Self, MolarMassValidationError>

Creates an element mass contribution.

Errors

Returns a molar-mass validation error when the symbol, atomic mass, count, or calculated contribution is invalid.

pub fn symbol(&self) -> &str

Returns the element symbol.

pub const fn atomic_mass(&self) -> f64

Returns the atomic mass in grams per mole.

pub const fn count(&self) -> u32

Returns the element count in the formula.

pub fn total_mass_value(&self) -> f64

Returns the contribution value in grams per mole.

pub fn total_molar_mass(&self) -> Result<MolarMass, MolarMassValidationError>

Returns the contribution as a molar mass value in grams per mole.

Errors

Returns a molar-mass validation error if the calculated contribution is invalid.

Trait Implementations

impl Clone for ElementMassContribution

fn clone(&self) -> ElementMassContribution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElementMassContribution

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

Formats the value using the given formatter.

impl Display for ElementMassContribution

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

Formats the value using the given formatter.

impl PartialEq for ElementMassContribution

fn eq(&self, other: &ElementMassContribution) -> 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.
