Struct chemfiles::Match
[−]
[src]
pub struct Match(_);
A Match
is a set of atomic indexes matching a given selection. It can
mostly be used like a &[u64]
.
Methods
impl Match
[src]
pub fn len(&self) -> usize
[src]
Get the length of the Match.
Example
let atomic_match = Match::new(&[3, 4, 5]); assert_eq!(atomic_match.len(), 3);
pub fn new(atoms: &[u64]) -> Match
[src]
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);
pub fn iter(&self) -> Iter<u64>
[src]
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);
