Module meta 

SigMF recording metadata: the contents of a .sigmf-meta file.

A SigMF metadata document is a JSON object with three required top-level keys, each modeled by its own type:

• global — recording-wide properties such as core:datatype, core:sample_rate, and core:version (crate::global::Global);
• captures — segments of the dataset keyed by core:sample_start (crate::capture::Capture);
• annotations — labeled sample and frequency ranges (crate::annotation::Annotation).

Metadata ties these together, parses and serializes the document (preserving unknown extension keys), offers range queries over captures and annotations, and writes validated metadata to disk. MetadataEdit provides transactional, validate-then-commit editing, and MetadataChange describes differences reported by Metadata::diff.
