Struct rocket::config::Ident

source ·
pub struct Ident(/* private fields */);
Expand description

An identifier (or None) to send as the Server header.

Deserialization

An Ident deserializes from any of the following:

  • string

    The string must be a valid Ident. See Ident::try_new() for details.

  • boolean

    The boolean must be false. The value will be Ident::none().

  • Option<string>

    If Some, this is the same as deserializing from the inner string. If None, the value is Ident::none().

  • unit

    Always deserializes as Ident::none().

Examples

As with all Rocket configuration options, when using the default Config::figment(), Ident can be configured via a Rocket.toml file. When no value for ident is provided, the value defaults to "Rocket". Because a default is provided, configuration only needs to provided to customize or remove the value.

use rocket::config::{Config, Ident};

// If these are the contents of `Rocket.toml`...
[default]
ident = false

// The config parses as follows:
assert_eq!(config.ident, Ident::none());

// If these are the contents of `Rocket.toml`...
[default]
ident = "My Server"

// The config parses as follows:
assert_eq!(config.ident, Ident::try_new("My Server").unwrap());

The following example illustrates manual configuration:

use rocket::config::{Config, Ident};

let figment = rocket::Config::figment().merge(("ident", false));
let config = rocket::Config::from(figment);
assert_eq!(config.ident, Ident::none());

let figment = rocket::Config::figment().merge(("ident", "Fancy/1.0"));
let config = rocket::Config::from(figment);
assert_eq!(config.ident, Ident::try_new("Fancy/1.0").unwrap());

Implementations§

source§

impl Ident

source

pub fn try_new<S: Into<String>>(ident: S) -> Result<Ident, String>

Returns a new Ident with the string ident.

When configured as the Config::ident, Rocket will set a Server header with the ident value on all responses.

Errors

The string ident must be non-empty and may only contain visible ASCII characters. The first character cannot be whitespace. The only whitespace characters allowed are (space) and \t (horizontal tab). The string is returned wrapped in Err if it contains any invalid characters.

Example
use rocket::config::Ident;

let ident = Ident::try_new("Rocket").unwrap();
assert_eq!(ident.as_str(), Some("Rocket"));

let ident = Ident::try_new("Rocket Run").unwrap();
assert_eq!(ident.as_str(), Some("Rocket Run"));

let ident = Ident::try_new(" Rocket");
assert!(ident.is_err());

let ident = Ident::try_new("Rocket\nRun");
assert!(ident.is_err());

let ident = Ident::try_new("\tShip");
assert!(ident.is_err());
source

pub const fn none() -> Ident

Returns a new Ident which is None.

When configured as the Config::ident, Rocket will not set a Server header on any response. Any Server header emitted by the application will still be written out.

Example
use rocket::config::Ident;

let ident = Ident::none();
assert_eq!(ident.as_str(), None);
source

pub fn as_str(&self) -> Option<&str>

Returns self as an Option<&str>.

Example
use rocket::config::Ident;

let ident = Ident::try_new("Rocket").unwrap();
assert_eq!(ident.as_str(), Some("Rocket"));

let ident = Ident::try_new("Rocket/1 (Unix)").unwrap();
assert_eq!(ident.as_str(), Some("Rocket/1 (Unix)"));

let ident = Ident::none();
assert_eq!(ident.as_str(), None);
