Struct ResourceTable

Source
pub struct ResourceTable {
    pub imported: bool,
    pub data: ResourceData,
}
Expand description

Map used for resource function bindgen within a given component

Mapping from the instance + resource index in that component (internal or external) to the unique global resource id used to key the resource tables for this resource.

The id value uniquely identifies the resource table so that if a resource is used by n components, there should be n different indices and spaces in use. The map is therefore entirely unique and fully distinct for each instance’s function bindgen.

The second bool is true if it is an imported resource.

For a given resource table id {x}, with resource index {y} the local variables are assumed:

  • handleTable{x}
  • captureTable{y} (rep to instance map for captured imported tables, only for JS import bindgen, not hybrid)
  • captureCnt{y} for assigning capture rep

For component-defined resources:

  • finalizationRegistry{x}

handleTable internally will be allocated with { rep: i32, own: bool } entries

In the case of an imported resource tables, in place of “rep” we just store the direct JS object being referenced, since in JS the object is its own handle.
