Struct ToonParser 

pub struct ToonParser { /* private fields */ }

TOON-LD Parser

Parses TOON-LD format back to JSON/JSON-LD values. The parser handles:

• Indented key-value pairs
• Tabular arrays (CSV format with header)
• Primitive arrays (inline or multi-line)
• Quoted and unquoted string values

Example

use toon_core::ToonParser;

let parser = ToonParser::new();
let toon = r#"
name: Alice
age: 30
"#;

let value = parser.parse(toon).unwrap();
assert_eq!(value.get("name").unwrap(), "Alice");
assert_eq!(value.get("age").unwrap(), 30);

Implementations

impl ToonParser

pub fn new() -> ToonParser

Create a new parser with default settings.

Example

use toon_core::ToonParser;

let parser = ToonParser::new();

pub fn with_context(self, context: JsonLdContext) -> ToonParser

Set the JSON-LD context for URI expansion.

Arguments

• context - The JSON-LD context to use

Example

use toon_core::{ToonParser, JsonLdContext};

let mut ctx = JsonLdContext::new();
ctx.add_prefix("foaf", "http://xmlns.com/foaf/0.1/");

let parser = ToonParser::new().with_context(ctx);

pub fn context(&self) -> &JsonLdContext

Get a reference to the current context.

pub fn parse(&self, input: &str) -> Result<Value, ToonError>

Parse TOON-LD string to JSON value.

Arguments

• input - The TOON-LD string to parse

Returns

A Result containing the parsed JSON value or an error.

Example

use toon_core::ToonParser;

let parser = ToonParser::new();
let value = parser.parse("name: Alice\nage: 30").unwrap();

assert_eq!(value.get("name").unwrap(), "Alice");

pub fn parse_to_json(&self, input: &str) -> Result<String, ToonError>

Parse TOON-LD string to pretty-printed JSON string.

Arguments

• input - The TOON-LD string to parse

Returns

A Result containing the JSON string or an error.

Example

use toon_core::ToonParser;

let parser = ToonParser::new();
let json = parser.parse_to_json("name: Alice").unwrap();

assert!(json.contains("\"name\""));
assert!(json.contains("\"Alice\""));
