Delim
This crate helps with parsing delimited from strings.
Usage Examples
The following shows how to retrieve a value from a string wrapped by matched delimiters:
let d = Delimited::new("abc:12:def");
assert_eq!(d.matched(":"), Some(12));
Consuming Delimited
The following shows how using a Delimited instance along with consume_matched can be used to extract two different delimited values from a string.
let mut d = Delimited::new("aaa :12: bbb :34: ccc");
// Consume first value (expecting 12)
let first = d.consume_matched(":");
// Consume second value (expecting 34)
let second = d.consume_matched(":");
assert_eq!(first, Some(12));
assert_eq!(second, Some(34));
Delimited Pattern Types
There are three primary delimited pattern types:
- Matched delimiters
- Mismatched delimiters
- Prefixed
Matched Delimiters Example
In the following string, the value 12 is wrapped by matched ":" delimiters.
abc:12:def
Mismatched Delimiters Example
In this string, the value 12 is wrapped by mismatched ":" and "<" delimiters.
abc:12<def
Prefixed Example
In this string, we decide that the value 12 is prefixed by |.
abc|12def
Prefixed delimiter searches requires the value length to be specified.
