Function parse_attributes 

pub fn parse_attributes(input: &str) -> Result<HashMap<String, String>, String>

Parses attributes from a given input string and returns a map of key-value pairs.

This function processes an input string formatted as key-value pairs separated by commas. Each key-value pair is expected to be in the format key="value". The function will trim the quotes around the values and construct a HashMap containing the parsed attributes.

Arguments

• input - A string containing the attributes to be parsed. The expected format is key1="value1",key2="value2",....

Returns

A result containing a HashMap<String, String> of attributes if parsing is successful, or an error message as a string if an error occurs during parsing.

Example

use m3u8_parser::m3u8::parser::parse_attributes;
let input = r#"METHOD="AES-128",URI="https://example.com/key",IV="1234567890abcdef""#;
let attributes = parse_attributes(input).expect("Failed to parse attributes");
assert_eq!(attributes.get("METHOD"), Some(&"AES-128".to_string()));
assert_eq!(attributes.get("URI"), Some(&"https://example.com/key".to_string()));
