Macro fixed_vec

macro_rules! fixed_vec {
    () => { ... };
    ($($elem:expr),+ $(,)?) => { ... };
    ($elem:expr; $len:expr) => { ... };
}

Creates a FixedVec with default parameters.

This macro simplifies the creation of FixedVec by using default parameters (usize for the storage word, LittleEndian for byte order) inferred from the element type. It uses BitWidth::Minimal for space efficiency.

There are three forms of this macro:

• Create a vector from a list of elements:

  let vec = fixed_vec![10u32, 20, 30];

• Create a vector from a repeated element:

  let vec = fixed_vec![0i16; 100];

• Create an empty vector (the element type must be specified):

  let vec: UFixedVec<u32> = fixed_vec![];

Examples

use compressed_intvec::fixed_vec;
use compressed_intvec::fixed::UFixedVec;

// Create a vector from a list of elements.
let vec = fixed_vec![10u32, 20, 30];
assert_eq!(vec.len(), 3);
assert_eq!(vec.bit_width(), 5); // 30 requires 5 bits

// Create a vector from a repeated element.
let vec_rep = fixed_vec![0i16; 100];
assert_eq!(vec_rep.len(), 100);
assert_eq!(vec_rep.get(50), Some(0));

// Create an empty vector (type annotation is required).
let empty: UFixedVec<u64> = fixed_vec![];
assert!(empty.is_empty());
