//! The creation and processing of number format packed structs.
//!
//! This creates the format specification as a 128-bit packed struct,
//! represented as a [`u128`] through the [`NumberFormatBuilder`] and
//! with helpers to access format options through [`NumberFormat`].
//!
//! This has a consistent API whether or not the [`format`][crate#features]
//! feature is enabled, however, most functionality will be disabled if the
//! feature is not enabled.
//!
//! # Creating Formats
//!
//! Formats can be created through [`NumberFormatBuilder`]:
//!
//! ```rust
//! # #[cfg(feature = "format")] {
//! use core::num;
//!
//! use lexical_util::{NumberFormat, NumberFormatBuilder};
//!
//! // create the format for literal Rustt floats
//! const RUST: u128 = NumberFormatBuilder::new()
//! .digit_separator(num::NonZeroU8::new(b'_'))
//! .required_digits(true)
//! .no_positive_mantissa_sign(true)
//! .no_special(true)
//! .internal_digit_separator(true)
//! .trailing_digit_separator(true)
//! .consecutive_digit_separator(true)
//! .build_strict();
//!
//! // then, access the formats's properties
//! let format = NumberFormat::<{ RUST }> {};
//! assert!(format.no_positive_mantissa_sign());
//! assert!(format.no_special());
//! assert!(format.internal_digit_separator());
//! assert!(format.trailing_digit_separator());
//! assert!(format.consecutive_digit_separator());
//! assert!(!format.no_exponent_notation());
//! # }
//! ```
//!
//! These pre-built formats can then be used for [`FromLexicalWithOptions`]
//! and [`ToLexicalWithOptions`] conversions.
//!
//! # Pre-Defined Formats
//!
//! These are the pre-defined formats for parsing numbers from various
//! programming, markup, and data languages.
//!
//! - [`STANDARD`]: Standard number format. This is identical to the Rust string
//! format.
