Struct ParserOptions 

pub struct ParserOptions {
    pub directives: bool,
    pub nondeterministic_hints: bool,
}

Options for a single parse_with run.

The default reproduces plain SYNX 3.7 behaviour; the non-default settings exist for embedded parses, where the host format owns the directive surface and the SYNX document is untrusted payload.

Fields

directives: bool

Recognise !-prefixed directive lines (!active, !lock, !tool, !schema, !llm, !include, !use) and the #!mode: pragma.

SYNXL block delegation sets this to false (SYNXL §9.4): a record that originates from an untrusted dataset must not be able to turn !include into a file-read primitive against the consuming process, nor flip the document into !active mode.

Neutralisation happens inside this parser, after the multiline-block check, so that | / |+ bodies keep their ! lines verbatim — a pre-filter over the raw lines would corrupt those bodies.

nondeterministic_hints: bool

Honour the random, random:int, random:float and random:bool type hints.

SYNXL block delegation sets this to false (SYNXL §8.3): a hint carried by dataset data would make the §12 projection differ between two reads of the same bytes, which defeats hashing, deduplication and the byte-identical projection §1.4 is measured on. Disabled, the hints fall back to automatic casting like any other unrecognised hint.
