//! Parse [SMuFL][smufl] (Standard Music Font Layout) metadata.
//!
//! SMuFL-compliant fonts can provide a metadata file in JSON format in their
//! distribution package. The metadata file allows the designer to provide
//! information that cannot easily (or in some cases at all) be encoded within
//! or retrieved from the font software itself, including recommendations for
//! how to draw the elements of music notation not provided directly by the font
//! itself (such as staff lines, barlines, hairpins, etc.) in a manner
//! complementary to the design of the font, and important glyph-specific
//! metrics, such as the precise coordinates at which a stem should connect to a
//! notehead.
//!
//! See the [SMuFL documentation][smufl-metadata] for more details.
//!
//! This crate supports [version 1.40][smufl-version-history] of the SMuFL
//! specification.
//!
//! The font metadata can be read into the [`Metadata`](crate::Metadata) struct:
//!
//! ```
//! use std::{fs::File, io::BufReader};
//!
//! use smufl::{Glyph, Metadata, StaffSpaces};
//!
//! # fn example() -> anyhow::Result<()> {
//! let file = File::open("../submodules/bravura/redist/bravura_metadata.json")?;
//! let reader = BufReader::new(file);
//! let metadata = Metadata::from_reader(reader)?;
//!
//! assert_eq!(metadata.font_name, "Bravura");
//! assert_eq!(
//!     metadata.engraving_defaults.staff_line_thickness.unwrap(),
//!     StaffSpaces(0.13)
//! );
//! assert_eq!(
//!     metadata.advance_widths.get(Glyph::NoteheadWhole),
//!     StaffSpaces(1.688)
//! );
//! assert_eq!(
//!     metadata
//!         .anchors
//!         .get(Glyph::NoteheadBlack)
//!         .stem_up_se
//!         .unwrap()
//!         .x(),
//!     StaffSpaces(1.18)
//! );
//! assert_eq!(
//!     metadata.bounding_boxes.get(Glyph::NoteheadBlack).ne.x(),
//!     StaffSpaces(1.18)
//! );
//! # Ok(())
//! # }
//! # example().unwrap()
//! ```
