Struct Configuration

#[non_exhaustive]
pub struct Configuration {
    pub classification: Option<String>,
    pub configurations: Option<Vec<Configuration>>,
    pub properties: Option<HashMap<String, String>>,
}

Amazon EMR releases 4.x or later.

An optional configuration specification to be used when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR. A configuration consists of a classification, properties, and optional nested configurations. A classification refers to an application-specific configuration file. Properties are the settings you want to change in that file. For more information, see Configuring Applications.

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.

classification: Option<String>

The classification within a configuration.

configurations: Option<Vec<Configuration>>

A list of additional configurations to apply within a configuration object.

properties: Option<HashMap<String, String>>

A set of properties specified within a configuration classification.

Implementations

impl Configuration

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

The classification within a configuration.

pub fn configurations(&self) -> &[Configuration]

A list of additional configurations to apply within a configuration object.

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

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

A set of properties specified within a configuration classification.

impl Configuration

pub fn builder() -> ConfigurationBuilder

Creates a new builder-style object to manufacture Configuration.

Trait Implementations

impl Clone for Configuration

fn clone(&self) -> Configuration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Configuration

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

Formats the value using the given formatter.

impl PartialEq for Configuration

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