[−][src]Enum rocket::config::Environment
An enum corresponding to the valid configuration environments.
Variants
The development environment.
The staging environment.
The production environment.
Methods
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());

impl Copy for Environment
[src]
impl Debug for Environment
[src]
impl Display for Environment
[src]
impl Eq for Environment
[src]
impl FromStr for Environment
[src]
type Err = ()
The associated error which can be returned from parsing.
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);
