Enum Contribution 

pub enum Contribution {
    System(SystemDecl),
    Resource(ResourceDecl),
    Plugin(&'static str),
    ServiceDomain(String),
}

Declarative interface from WASM plugin to Host.

A WASM plugin’s plugin_build() returns a list of Contributions describing what the plugin wants to add to the Bevy App. The Host applies these contributions after collecting them from all plugins.

The plugin never receives &mut App directly.

Variants

System(SystemDecl)

Resource(ResourceDecl)

Add a resource with a default value.

Plugin(&'static str)

Add a known Bevy Plugin (referenced by name).

ServiceDomain(String)

Reserve a service domain (prevents conflicts).
