Implementations

impl Environment

pub fn init() -> Result<Self>

Get the value from the environment variable APP_ENV. It raise an error if the string doesn’t match a possible environment.

Examples

use std::env;
use server_env_config::env::Environment;

env::set_var("APP_ENV", "production");
assert!(matches!(Environment::init(), Ok(Environment::Production)));
env::set_var("APP_ENV", "Not a environment");
assert!(Environment::init().is_err());
env::remove_var("APP_ENV"); // if not set, local environment is the default
assert!(matches!(Environment::init(), Ok(Environment::Local)));

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Environment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Environment

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

Formats the value using the given formatter.

impl Default for Environment

fn default() -> Environment

Returns the “default value” for a type.

impl Display for Environment

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

Formats the value using the given formatter.

impl FromStr for Environment

type Err = ParseError

The associated error which can be returned from parsing.

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

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

impl PartialEq for Environment

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for Environment

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Environment, <Self as TryFrom<&str>>::Error>

Performs the conversion.
