A slice containing primitive values.

The Slice enum is used to pass multiple primitive-values to the visitor. This is used as an optimization when visiting Listable types to avoid a dynamic dispatch call to Visit for each element in the collection.

Slice instances are usually not created explicitly. Instead, they are created when calling Valuable::visit_slice().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Examples

use valuable::Slice;

let v = Slice::Bool(&[true, true, false]);

Implementations

impl<'a> Slice<'a>

pub fn len(&self) -> usize

Returns the number of elements in the slice

Examples

use valuable::Slice;

let slice = Slice::U32(&[1, 1, 2, 3, 5]);
assert_eq!(5, slice.len());

pub fn is_empty(&self) -> bool

Returns true if the slice is not empty.

Examples

use valuable::Slice;

let slice = Slice::U32(&[1, 1, 2, 3, 5]);
assert!(!slice.is_empty());

let slice = Slice::U32(&[]);
assert!(slice.is_empty());

pub fn iter(&self) -> Iter<'a>

Returns an iterator over the slice.

Examples

use valuable::Slice;

let slice = Slice::U32(&[1, 1, 2, 3, 5]);

for value in slice.iter() {
    println!("{:?}", value);
}
