Crate embed_constvec 

A fixed-size inline vector with const generic capacity.

Features

• It’s smaller in size than std::vec::Vec.
• push returns errors when the capacity is exceeded instead of reallocating.
• No heap allocation after initial creation, better cache consistency.
• If you want heap allocation, use Box<ConstVec<T, N>>.

Example

use embed_constvec::ConstVec;

let mut vec: ConstVec<i32, 3> = ConstVec::new();

assert!(vec.push(1).is_ok());
assert!(vec.push(2).is_ok());
assert!(vec.push(3).is_ok());

// Capacity is full, next push returns Err
assert!(vec.push(4).is_err());

assert_eq!(vec.len(), 3);
assert_eq!(vec.capacity(), 3);
