Struct Element 

pub struct Element(/* private fields */);

A chemical element, identified by its atomic number Z — the proton count.

Implementations

impl Element

pub const fn new(z: u8) -> Option<Self>

Constructs an element from atomic number z, returning None if z is zero.

pub const fn from_nonzero(z: NonZeroU8) -> Self

Constructs an element from a NonZeroU8 atomic number directly.

pub fn from_symbol(symbol: &str) -> Option<Self>

Constructs an element from its symbol (e.g. "C", "Og", "Uue"), returning None if no element has that symbol.

The exact, case-sensitive inverse of symbol.

pub const fn atomic_number(self) -> u8

Returns the atomic number Z (the proton count), always greater than zero.

pub fn symbol(self) -> &'static str

Returns the element symbol (e.g. "C", "Og").

Elements with Z > 118 return their IUPAC systematic symbol (e.g. "Uue").

pub fn name(self) -> &'static str

Returns the element name (e.g. "Carbon", "Oganesson").

Elements with Z > 118 return their IUPAC systematic name (e.g. "Ununennium").

pub const fn period(self) -> Option<u8>

Returns the period (periodic-table row, 1..=7), or None for Z > 118.

Trait Implementations

impl Clone for Element

fn clone(&self) -> Element

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Element

impl Debug for Element

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

Formats the value using the given formatter.

impl Display for Element

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

Formats the value using the given formatter.

impl Eq for Element

impl Hash for Element

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Element

fn cmp(&self, other: &Element) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Element

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

impl PartialOrd for Element

fn partial_cmp(&self, other: &Element) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
