Struct WitWorld 

pub struct WitWorld {
    pub imports: HashSet<WitInterface>,
    pub exports: HashSet<WitInterface>,
}

A collection of WIT interfaces representing a world definition.

A WIT world describes the imports and exports that a component or plugin provides. This is used for capability matching between workloads and plugins.

Fields

imports: HashSet<WitInterface>

The interfaces that this world imports (requires from the host)

exports: HashSet<WitInterface>

The interfaces that this world exports (provides to the host)

Implementations

impl WitWorld

pub fn includes(&self, interface: &WitInterface) -> bool

This function checks if the world includes a specific interface. This is slightly different than checking directly against the imports or exports because it takes into account the possibility of interface nesting and versioning. See WitInterface::contains for more details.

pub fn includes_bidirectional(&self, interface: &WitInterface) -> bool

This function checks if the world includes a specific interface. This is different than WitWorld::includes because it considers that in one WitInterface there may be both imports and exports.

pub fn satisfies(&self, guest: &WitWorld) -> bool

Checks if a guest world (imports) can be satisfied by a host world (exports).

A host world satisfies a guest world if all interfaces required by the guest are provided by the host, considering interface containment (subset/superset) and ignoring any additional interfaces or versions in the host.

Arguments

• guest - The guest world to check

Returns

true if the host world (self) provides all interfaces required by the guest world through direct exports or through superset relationships.
