Struct WitInterface 

pub struct WitInterface {
    pub namespace: String,
    pub package: String,
    pub interfaces: HashSet<String>,
    pub version: Option<Version>,
    pub config: HashMap<String, String>,
}

Represents a WIT interface specification with namespace, package, and optional version.

A WitInterface identifies a specific set of interfaces from a WIT package. It follows the format: namespace:package/interface1,interface2@version where interfaces and version are optional.

Examples

• wasi:http - Just namespace and package
• wasi:http/incoming-handler - With a single interface
• wasi:http/incoming-handler,outgoing-handler@0.2.0 - Multiple interfaces with version

Fields

namespace: String

The namespace of the interface (e.g., “wasi”)

package: String

The package name (e.g., “http”, “blobstore”)

interfaces: HashSet<String>

The specific interfaces within the package (e.g., “incoming-handler”, “types”)

version: Option<Version>

Optional semantic version for the interface

config: HashMap<String, String>

Additional configuration parameters for this interface

Implementations

impl WitInterface

pub fn instance(&self) -> String

Returns the instance name of this WitInterface, aka the namespace:package@version identifier without the interfaces or config.

pub fn merge(&mut self, other: &WitInterface) -> bool

Merges another WitInterface into this one, returning a boolean indicating whether the merge was successful (aka if the WitInterface::instances matched).

pub fn contains(&self, other: &WitInterface) -> bool

Checks if this interface contains (is a superset of) another interface.

This method is used to determine if a plugin or component that provides this interface can satisfy a requirement for the other interface.

Arguments

• other - The interface to check against

Returns

true if:

• The namespace and package match exactly
• If this interface has a version, it must match the other’s version
• The other’s interfaces are a subset of this interface’s interfaces
