Crate pest_ion

Provides simple conversion from Pest grammar syntax to Amazon Ion.

Example

The easiest way to convert Pest grammars to Ion is from a str slice:

use pest_ion::*;
use ion_rs::value::*;
use ion_rs::value::reader::*;

fn main() -> PestToIonResult<()> {
    // parse a Pest grammar and convert it to Ion element
    let actual = r#"a = @{ "a" | "b" ~ "c" }"#.try_pest_to_element()?;

    // here is the equivalent Ion element
    let ion_text = r#"{
        a: {
            type: atomic,
            expression:
                (choice
                    (string exact "a")
                    (sequence
                        (string exact "b")
                        (string exact "c")
                    )
                )
        }
    }"#;
    let expected = element_reader().read_one(ion_text.as_bytes())?;

    // these should be equivalent
    assert_eq!(expected, actual);
     
    Ok(())
}
