basis-points

A small, validated basis-points type for Solana-oriented Rust code.

What it provides

• BasisPoints newtype with enforced range 0..=10_000
• Conversions to integer types (u16, u32, u64, u128)
• Optional rust_decimal conversions (BasisPoints ↔ proportional rate in 0..=1)
• Optional Anchor derives via feature flags

Install

cargo add basis-points

Features

• decimal: enable rust_decimal conversions
• anchor: enable Anchor serialization/IDL traits

Example

use basis_points::BasisPoints;

let fee = BasisPoints::new(25)?; // 0.25%
let raw: u16 = fee.into();
assert_eq!(raw, 25);
# Ok::<(), basis_points::BasisPointsError>(())
