FixedVec Builders

This module provides builders for constructing an owned FixedVec.

There are two main builders:

• FixedVecBuilder: For building from a slice (&[T]). It can automatically determine the optimal bit width from the data.
• FixedVecFromIterBuilder: For building from an iterator. This is useful for large datasets, but requires the bit width to be specified manually.

Examples

Building from a slice

use compressed_intvec::fixed::{FixedVec, BitWidth, UFixedVec};
use compressed_intvec::fixed::builder::FixedVecBuilder;

let data: &[u32] = &[10, 20, 30, 40, 50];

// The builder can infer the minimal bit width.
let vec: UFixedVec<u32> = FixedVecBuilder::new()
    .build(data)
    .unwrap();

assert_eq!(vec.bit_width(), 6); // 50 requires 6 bits

// Or a specific strategy can be chosen.
let vec_pow2: UFixedVec<u32> = FixedVecBuilder::new()
    .bit_width(BitWidth::PowerOfTwo)
    .build(data)
    .unwrap();

assert_eq!(vec_pow2.bit_width(), 8);

Structs

FixedVecBuilder

A builder for creating a FixedVec from a slice of integers.
