impl Tokenizer for DefaultTokenizer

fn index_parse(key: &str) -> Result<usize, IndexError>

Parse index array.

• should starts and end with ‘[’ and ‘]’. No space allowed.

use querable::{types::Tokenizer, default::DefaultTokenizer, error::{IndexError}};

assert_eq!(DefaultTokenizer::index_parse("[]"), Err(IndexError::ParseError(String::from("[]"))));

• index should be an integer, specificially, in the range of usize.

use querable::{types::Tokenizer, default::DefaultTokenizer};

assert!(DefaultTokenizer::index_parse("[x]").is_err());

fn dict_parse(key: &str) -> Result<State<'_>, KeyError>

Parse key/path index.

• shouldn’t be an empty string or being prefixed & suffixed with empty string.

use querable::{types::Tokenizer, default::DefaultTokenizer, error::{KeyError}};

assert_eq!(DefaultTokenizer::dict_parse("   .test"), Err(KeyError::ParseError(String::from("   "))));
assert_eq!(DefaultTokenizer::dict_parse(""), Err(KeyError::EmptyKey));
