Trait ident::IdentCollection

pub trait IdentCollection<T, I = usize> {
    fn insert_by_ident(
        &mut self, 
        value: WithIdent<T, I>
    ) -> Option<WithIdent<T, I>>;
    fn contains_ident(&self, identifier: &I) -> bool;
    fn get_with_ident(&self, identifier: I) -> Option<WithIdent<&T, I>>;
    fn get_mut_with_ident(
        &mut self, 
        identifier: I
    ) -> Option<WithIdent<&mut T, I>>;
}

The IdentCollection trait provides functionality for collections working with WithIdent values.

Required Methods

fn insert_by_ident(&mut self, value: WithIdent<T, I>) -> Option<WithIdent<T, I>>

Inserts the passed value or updates the first value found with an equal identifier.

If a value is updated the old value is returned in a Some(value).

Examples

let mut vec = Vec::with_capacity(1);
let a = WithIdent::new(1, 5);
let b = WithIdent::new(1, 10);

assert!(vec.insert_by_ident(a.clone()).is_none()); //Inserting.
assert_eq!(a, vec.insert_by_ident(b.clone()).unwrap()); //Updating.
assert_eq!(b, vec[0]); //Updated value.

fn contains_ident(&self, identifier: &I) -> bool

Searches for the passed identifier in the collection.

Params

identifier --- The identifier to seach for.

fn get_with_ident(&self, identifier: I) -> Option<WithIdent<&T, I>>

Attempts to retrieve a reference to the value with the passed identifier.

If a reference is found it is returned with the identifier attached.

Params

identifier --- The identifier to seach for.

fn get_mut_with_ident(&mut self, identifier: I) -> Option<WithIdent<&mut T, I>>

Attempts to retrieve a mutable reference to the value with the passed identifier.

If a reference is found it is returned with the identifier attached.

Params

identifier --- The identifier to seach for.
