Struct Application

#[non_exhaustive]
pub struct Application {
    pub name: Option<String>,
    pub version: Option<String>,
    pub args: Option<Vec<String>>,
    pub additional_info: Option<HashMap<String, String>>,
}

With Amazon EMR release version 4.0 and later, the only accepted parameter is the application name. To pass arguments to applications, you use configuration classifications specified using configuration JSON objects. For more information, see Configuring Applications.

With earlier Amazon EMR releases, the application is any Amazon or third-party software that you can add to the cluster. This structure contains a list of strings that indicates the software to use with the cluster and accepts a user argument list. Amazon EMR accepts and forwards the argument list to the corresponding installation script as bootstrap action argument.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Option<String>

The name of the application.

version: Option<String>

The version of the application.

args: Option<Vec<String>>

Arguments for Amazon EMR to pass to the application.

additional_info: Option<HashMap<String, String>>

This option is for advanced users only. This is meta information about third-party applications that third-party vendors use for testing purposes.

Implementations

impl Application

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

The name of the application.

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

The version of the application.

pub fn args(&self) -> &[String]

Arguments for Amazon EMR to pass to the application.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .args.is_none().

pub fn additional_info(&self) -> Option<&HashMap<String, String>>

This option is for advanced users only. This is meta information about third-party applications that third-party vendors use for testing purposes.

impl Application

pub fn builder() -> ApplicationBuilder

Creates a new builder-style object to manufacture Application.

Trait Implementations

impl Clone for Application

fn clone(&self) -> Application

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Application

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

Formats the value using the given formatter.

impl PartialEq for Application

fn eq(&self, other: &Application) -> 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.
