Constant FLOW_PLAIN_NEEDLES 

pub const FLOW_PLAIN_NEEDLES: &[u8] = b": \t,[]{}";

Canonical YAML 1.2 plain-scalar boundary candidate set inside flow collections ([ ], { }). Adds the flow-collection terminators (,, [, ], {, }) to the block set.

The wider needle set means the scanner sees more candidate boundaries per chunk in flow context — exactly the workload where StructuralIter’s 32-byte-bitmask discovery beats a per-candidate restart pattern.

Examples

use noyalib::simd::{FLOW_PLAIN_NEEDLES, SimdScanner};
let s = SimdScanner::new(FLOW_PLAIN_NEEDLES);
assert_eq!(s.find_any(b"hello, world"), Some(5));
