Struct assert_cli::Environment

pub struct Environment { /* fields omitted */ }

Structure to deal with environment variables

Methods

impl Environment

pub fn inherit() -> Environment

Create a new Environment that inherits this process' environment.

Examples

extern crate environment;
use std::ffi::OsString;

let e = environment::Environment::inherit().compile();
let e_: Vec<(OsString, OsString)> = ::std::env::vars_os().collect();

assert_eq!(e, e_);

pub fn empty() -> Environment

Create a new Environment independent of the current process's Environment

Examples

extern crate environment;

let e = environment::Environment::empty().compile();
assert_eq!(e, Vec::new());

pub fn insert<S1, S2>(self, key: S1, val: S2) -> Environment where     S1: Into<OsString>,     S2: Into<OsString>,

Insert a new entry into the custom variables for this environment object

Examples

extern crate environment;

use std::ffi::OsString;

let e = environment::Environment::empty().insert("foo", "bar").compile();
assert_eq!(e, vec![(OsString::from("foo"), OsString::from("bar"))]);

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Environment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Environment

fn default() -> Environment

Returns the "default value" for a type.

impl Debug for Environment

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for Environment

impl PartialEq<Environment> for Environment

fn eq(&self, other: &Environment) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Environment) -> bool

This method tests for !=.

impl<'s, T> From<T> for Environment where     T: IntoIterator,     <T as IntoIterator>::Item: EnvironmentItem,

fn from(v: T) -> Environment

Performs the conversion.

impl<'a> From<&'a Environment> for Environment

Implicit clone for ergonomics

fn from(v: &'a Environment) -> Environment

Performs the conversion.
