Struct chemfiles::Match

source ·
pub struct Match { /* private fields */ }
Expand description

A Match is a set of atomic indexes matching a given selection. It can mostly be used like a &[usize].

Implementations§

source§

impl Match

source

pub fn len(&self) -> usize

Get the length of the Match.

Example
let atomic_match = Match::new(&[3, 4, 5]);
assert_eq!(atomic_match.len(), 3);
source

pub fn new(atoms: &[usize]) -> Match

Create a new match containing the atoms in the atoms slice.

Panics

If the slice contains more than 4 elements, which is the maximal size of a match.

Example
let atomic_match = Match::new(&[3, 4, 5]);
assert_eq!(atomic_match.len(), 3);
assert_eq!(atomic_match[0], 3);
assert_eq!(atomic_match[1], 4);
assert_eq!(atomic_match[2], 5);
source

pub fn iter(&self) -> Iter<'_, usize>

Iterate over the atomic indexes in the match.

Example
let atomic_match = Match::new(&[3, 4, 5]);
let mut iter = atomic_match.iter();

assert_eq!(iter.next(), Some(&3));
assert_eq!(iter.next(), Some(&4));
assert_eq!(iter.next(), Some(&5));
assert_eq!(iter.next(), None);

impl PartialEq<Match> for Match

source§

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

1.0.0 · source§

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

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