Struct zenv::Lines[−][src]

pub struct Lines<'l> { /* fields omitted */ }

Expand description

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

[src]

impl<'l> Lines<'l>

[src]

pub fn new(lines: Vec<Line<'l>>) -> Self

Create Lines from a vec of Line. Can be useful if you manually parsing individual lines

Example

use zenv::{Lines, Line};

let lines = vec![
    Line::from("BASIC=basic"),
    Line::Empty,
    Line::from("QUOTED='quoted'")
];

let parsed = Lines::new(lines).to_hash_map();

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

[src]

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());

[src]

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());
