Struct zenv::Lines

pub struct Lines { /* fields omitted */ }

Lines is used to parse the sequence of lines

Zenv is built on top it. And if you want you can directly use this but don’t :)

Implementations

impl Lines

pub fn to_hash_map(&self) -> HashMap<String, String>

Parses the lines and converts into a hashmap

Example

use zenv::Lines;

const LINES: &str = r#"
BASIC=basic
QUOTED='quoted'
"#;

let parsed = Lines::from(LINES).to_hash_map();

assert_eq!(parsed.get("BASIC").unwrap(), &"basic".to_string());
assert_eq!(parsed.get("QUOTED").unwrap(), &"quoted".to_string());

pub fn expand(&self) -> HashMap<String, String>

Parses the lines and does variable substitution then converts into a hashmap

Example

use zenv::Lines;

const LINES: &str = r#"
BASIC=basic
EXPANDED="${BASIC}_is_expanded"
"#;

let parsed = Lines::from(LINES).expand();

assert_eq!(parsed.get("BASIC").unwrap(), &"basic".to_string());
assert_eq!(parsed.get("EXPANDED").unwrap(), &"basic_is_expanded".to_string());
