Struct chemfiles::ResidueRef

pub struct ResidueRef<'a> { /* fields omitted */ }

An analog to a reference to a residue (&Residue)

Methods from Deref<Target = Residue>

pub fn size(&self) -> u64

Get the number of atoms in this residue.

Example

let mut residue = Residue::new("water");
assert_eq!(residue.size(), 0);

residue.add_atom(0);
residue.add_atom(1);
residue.add_atom(2);
assert_eq!(residue.size(), 3);

pub fn id(&self) -> Option<u64>

Get the identifier of this residue in the initial topology file.

Example

let residue = Residue::with_id("", 42);
assert_eq!(residue.id(), Some(42));

pub fn name(&self) -> String

Get the name of this residue.

Example

let residue = Residue::new("water");
assert_eq!(residue.name(), "water");

pub fn contains(&self, atom: u64) -> bool

Check if the atom at index i is in this residue

Example

let mut residue = Residue::new("water");
assert_eq!(residue.contains(56), false);

residue.add_atom(56);
assert_eq!(residue.contains(56), true);

pub fn get(&self, name: &str) -> Option<Property>

Get a property with the given name in this frame, if it exist.

Examples

let mut residue = Residue::new("ALA");
residue.set("foo", Property::Double(22.2));

assert_eq!(residue.get("foo"), Some(Property::Double(22.2)));
assert_eq!(residue.get("Bar"), None);

Important traits for PropertiesIter<'a>

impl<'a> Iterator for PropertiesIter<'a> type Item = (String, Property);

pub fn properties(&self) -> PropertiesIter

Get an iterator over all (name, property) pairs for this frame

Examples

let mut residue = Residue::new("ALA");
residue.set("foo", Property::Double(22.2));
residue.set("bar", Property::Bool(false));

for (name, property) in residue.properties() {
    if name == "foo" {
        assert_eq!(property, Property::Double(22.2));
    } else if name == "bar" {
        assert_eq!(property, Property::Bool(false));
    }
}
