Expand description
Creates a LESIntVec
(an IntVec
of i64
s) containing the given elements.
sint_vec!
allows for concise initialization of a LESIntVec
, which is an
alias for IntVec<i64, LE>
. It uses a set of reasonable defaults:
- Codec:
VariableCodecSpec::Auto
is used to automatically select the best codec based on the data’s properties (via zig-zag encoding). - Sampling Rate (
k
): A default value of16
is used.
§Note on Types
All input elements are automatically cast to i64
.
For more control over these parameters, or to use a different integer type,
please use the IntVec::builder
.
§Examples
Create an empty LESIntVec
:
let v: LESIntVec = sint_vec![];
assert!(v.is_empty());
Create an LESIntVec
from a list of elements:
let v: LESIntVec = sint_vec![-100, 200, -300];
assert_eq!(v.len(), 3);
assert_eq!(v.get(2), Some(-300));
Create an LESIntVec
with a repeated element:
let v: LESIntVec = sint_vec![-42; 100];
assert_eq!(v.len(), 100);
assert_eq!(v.get(50), Some(-42));
