Module hed 

HED (Hierarchical Event Descriptors) tag parsing.

BIDS events files may include a HED column containing HED tags that describe events in a structured, hierarchical vocabulary. This module provides basic parsing and access to HED tag strings.

See: https://www.hedtags.org/ and https://bids-specification.readthedocs.io/en/stable/appendices/hed.html

Example

use bids_core::hed::{parse_hed_string, HedTag};

let tags = parse_hed_string("Sensory-event, Visual-presentation, (Item/Object/Man-made/Vehicle/Car, Color/Red)");
assert_eq!(tags.len(), 3);
assert_eq!(tags[0].tag, "Sensory-event");
assert!(tags[2].is_group());
