Enum rocket::config::Environment[][src]

pub enum Environment {
    Development,
    Staging,
    Production,
}
Expand description

An enum corresponding to the valid configuration environments.

Variants

Development

The development environment.

Staging

The staging environment.

Production

The production environment.

Implementations

impl Environment[src]

pub fn active() -> Result<Environment, ConfigError>[src]

Retrieves the “active” environment as determined by the ROCKET_ENV environment variable. If ROCKET_ENV is not set, returns Development when the application was compiled in debug mode and Production when the application was compiled in release mode.

Errors

Returns a BadEnv ConfigError if ROCKET_ENV is set and contains an invalid or unknown environment name.

pub fn is_dev(self) -> bool[src]

Returns true if self is Environment::Development.

Example

use rocket::config::Environment;

assert!(Environment::Development.is_dev());
assert!(!Environment::Production.is_dev());

pub fn is_stage(self) -> bool[src]

Returns true if self is Environment::Staging.

Example

use rocket::config::Environment;

assert!(Environment::Staging.is_stage());
assert!(!Environment::Production.is_stage());

pub fn is_prod(self) -> bool[src]

Returns true if self is Environment::Production.

Example

use rocket::config::Environment;

assert!(Environment::Production.is_prod());
assert!(!Environment::Staging.is_prod());

Trait Implementations

impl Clone for Environment[src]

fn clone(&self) -> Environment[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

impl FromStr for Environment[src]

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

Parses a configuration environment from a string. Should be used indirectly via str’s parse method.

Examples

Parsing a development environment:

use rocket::config::Environment;

let env = "development".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Development);

let env = "dev".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Development);

let env = "devel".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Development);

Parsing a staging environment:

use rocket::config::Environment;

let env = "staging".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Staging);

let env = "stage".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Staging);

Parsing a production environment:

use rocket::config::Environment;

let env = "production".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Production);

let env = "prod".parse::<Environment>();
assert_eq!(env.unwrap(), Environment::Production);

type Err = ()

The associated error which can be returned from parsing.

impl Hash for Environment[src]

fn hash<__H: Hasher>(&self, state: &mut __H)[src]

Feeds this value into the given Hasher. Read more

fn hash_slice<H>(data: &[Self], state: &mut H) where

#[must_use]
fn ne(&self, other: &Rhs) -> bool
1.0.0[src]

This method tests for !=.
