3//! General-purpose traits for generic Rust programming.
4//!
5//! The crate supplies small traits for concepts that are
6//! useful across unrelated types, including [`IsEmpty`],
7//! [`Len`], [`ToF64`], and [`Zero`]. Implementations for
8//! built-in and standard-library types are controlled by
9//! feature flags so consumers can choose the API surface
10//! they need.
11//!
12//! # Example
13//!
14//! ```
15//! use base_traits::ToF64;
16//!
17//! struct Price(f64);
18//!
19//! impl ToF64 for Price {
20//!     fn to_f64(&self) -> f64 {
21//!         self.0
22//!     }
23//! }
24//!
25//! let price = Price(12.50);
26//! assert_eq!(12.50, price.to_f64());
27//! ```
28//!
29//! The default feature set enables the common built-in and
30//! standard-library implementations. The `"full"` feature
31//! enables the broader set, including the experimental
32//! process-type implementations. Use `"nostd"` when the
33//! standard library is unavailable.
