How do I serialize a pattern to Gram notation?

Serialization converts a list of Pattern<Subject> values back to a Gram notation string. The result is a valid Gram document that can be parsed again.

Rust

use gram_codec::{parse_gram, to_gram};

let patterns = parse_gram("(alice:Person)")?;
let output = to_gram(&patterns)?;

println!("{}", output); // (alice:Person)

Python

from relateby import gram

patterns = gram.parse("(alice:Person)")
output = gram.stringify(patterns)

print(output)  # (alice:Person)

TypeScript

import { Gram } from "@relateby/gram"
import { Effect, pipe } from "effect"

const output = await Effect.runPromise(
  pipe(
    Gram.parse("(alice:Person)"),
    Effect.flatMap(Gram.stringify)
  )
)

console.log(output) // (alice:Person)
