}Expand description
Creates a LEVarVec (a VarVec of u64s) containing the given elements.
int_vec! allows for concise initialization of a LEVarVec, which is an
alias for VarVec<u64, LE>. It uses a set of reasonable defaults for its
build parameters:
- Codec:
Codec::Autois used to automatically select the most space-efficient codec for the provided data. - Sampling Rate (
k): A default value of16is used, offering a good balance between random access speed and memory overhead.
§Note on Types
The macro infers the element type from the input. For explicit control over
parameters, use VarVec::builder.
§Examples
Create an empty LEVarVec:
let v: LEVarVec = int_vec![];
assert!(v.is_empty());Create a crate::variable::VarVec from a list of elements:
let v = int_vec![100u32, 200, 300, 1024];
assert_eq!(v.len(), 4);
assert_eq!(v.get(1), Some(200));Create a crate::variable::VarVec with a repeated element:
let v = int_vec![42u8; 100];
assert_eq!(v.len(), 100);
assert_eq!(v.get(50), Some(42));
