Trait Implementations

impl Clone for ExtStr

fn clone(&self) -> ExtStr

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl FromStr for ExtStr

Parses a string like name=<value>, or name and reads value from env variable. With no value it will be read from env variable. If env variable is not found then it will be an error. Value can contain = symbol.

use std::str::FromStr;
use jrsonnet_cli::ExtStr;

let ext = ExtStr::from_str("name=value").unwrap();
assert_eq!(ext.name, "name");
assert_eq!(ext.value, "value");

std::env::set_var("name", "value");

let ext = ExtStr::from_str("name").unwrap();
assert_eq!(ext.name, "name");
assert_eq!(ext.value, "value");

let ext = ExtStr::from_str("name=value=with=equals").unwrap();
assert_eq!(ext.name, "name");
assert_eq!(ext.value, "value=with=equals");

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
