Implementations

impl Environment

pub fn from_env() -> Result<Self>

Load environment from default env APP_ENVIRONMENT. Return Result of Environment. If env APP_ENVIRONMENT is not set, return Ok(Environment::default()).

Example

let environment = Environment::from_env().unwrap();

pub fn from_custom_env(key: &str) -> Result<Self>

Load environment from given env. Return Result of Environment. If env APP_ENVIRONMENT is not set, return Ok(Environment::default()).

Example

let environment = Environment::from_custom_env("CUSTOM_ENVIRONMENT").unwrap();

Trait Implementations

impl Debug for Environment

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

Formats the value using the given formatter.

impl Default for Environment

fn default() -> Self

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.
