Struct AtomicMassLookup 

pub struct AtomicMassLookup { /* private fields */ }

A caller-controlled element atomic-mass lookup table.

Implementations

impl AtomicMassLookup

pub const fn new() -> Self

Creates an empty lookup table.

pub fn from_entries(entries: impl IntoIterator<Item = AtomicMassEntry>) -> Self

Creates a lookup table from validated entries.

pub fn from_pairs<'a>( entries: impl IntoIterator<Item = (&'a str, f64)>, ) -> Result<Self, MolarMassValidationError>

Creates a lookup table from symbol and mass pairs.

Errors

Returns a molar-mass validation error when any entry is invalid.

pub fn from_formula( formula: &ChemicalFormula, ) -> Result<Self, MolarMassValidationError>

Creates a lookup table for the symbols present in a formula using RustUse atomic masses.

Errors

Returns MolarMassValidationError::MissingAtomicMass if a formula symbol is not present in the RustUse atomic-mass table. Returns another molar-mass validation error if a generated entry is invalid.

pub fn insert(&mut self, entry: AtomicMassEntry) -> Option<f64>

Inserts a validated atomic mass entry and returns the previous value, if any.

pub fn insert_atomic_mass( &mut self, symbol: &str, atomic_mass: f64, ) -> Result<Option<f64>, MolarMassValidationError>

Validates and inserts an atomic mass entry.

Errors

Returns a molar-mass validation error when the symbol or atomic mass is invalid.

pub fn atomic_mass(&self, symbol: &str) -> Option<f64>

Returns the atomic mass for a symbol.

pub fn entry(&self, symbol: &str) -> Option<AtomicMassEntry>

Returns a copy of the stored entry for a symbol.

pub fn contains_symbol(&self, symbol: &str) -> bool

Returns true when the lookup contains a symbol.

pub fn len(&self) -> usize

Returns the number of stored entries.

pub fn is_empty(&self) -> bool

Returns true when the lookup table is empty.

pub fn iter(&self) -> impl Iterator<Item = (&str, f64)> + '_

Iterates over stored symbol and atomic-mass pairs in symbol order.

Trait Implementations

impl Clone for AtomicMassLookup

fn clone(&self) -> AtomicMassLookup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtomicMassLookup

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

Formats the value using the given formatter.

impl Default for AtomicMassLookup

fn default() -> AtomicMassLookup

Returns the “default value” for a type.

impl PartialEq for AtomicMassLookup

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