Fields§

§name: Name

The name of the child component instance, which is a string of one or more of the following characters: a-z, 0-9, _, ., -. The name identifies this component when used in a reference.

§url: Url

The [component URL][component-url] for the child component instance.

§startup: StartupMode

The component instance’s startup mode. One of:

  • lazy (default): Start the component instance only if another component instance binds to it.
  • [eager][doc-eager]: Start the component instance as soon as its parent starts.
§on_terminate: Option<OnTerminate>

Determines the fault recovery policy to apply if this component terminates.

  • none (default): Do nothing.
  • reboot: Gracefully reboot the system if the component terminates for any reason. This is a special feature for use only by a narrow set of components; see [Termination policies][doc-reboot-on-terminate] for more information.
§environment: Option<EnvironmentRef>

If present, the name of the environment to be assigned to the child component instance, one of environments. If omitted, the child will inherit the same environment assigned to this component.

impl MarkdownReferenceDocGenerator for Child

source§

fn get_reference_doc_markdown() -> String

§

fn get_reference_doc_markdown_with_options( indent_headers_by: usize, indent_with_spaces: usize ) -> String

This method is called internally by the reference doc generator when recursing to generate documentation for field types.
source§

impl PartialEq for Child

source§

fn eq(&self, other: &Child) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
