Struct CapabilityRequest 

pub struct CapabilityRequest<T = Vec<u8>> {
    pub capability: String,
    pub action: String,
    pub payload: T,
    pub content_type: CapabilityContentType,
}

A serialized capability invocation request.

Default T = Vec<u8> is the on-wire form. Any T: WirePayload can go onto the wire via self.into_wire() (which calls WirePayload::into_wire_bytes on the payload and updates content_type).

Fields

capability: String

Matches a registered WasmCapability::name().

action: String

The action to perform (e.g. “read”, “write”, “capture”).

payload: T

The typed payload.

content_type: CapabilityContentType

Payload encoding.

Implementations

impl<T: WirePayload> CapabilityRequest<T>

pub fn into_wire(self) -> CapabilityRequest<Vec<u8>>

Convert a typed request into the wire form.

Calls WirePayload::into_wire_bytes(self.payload) and sets content_type from the result.

pub fn wire( capability: impl Into<String>, action: impl Into<String>, payload: T, ) -> CapabilityRequest<Vec<u8>>

Create a wire request from typed parts. Convenience: equivalent to CapabilityRequest { .. }.into_wire().

impl CapabilityRequest<Vec<u8>>

pub fn into_typed<T: WirePayload>( self, ) -> Result<CapabilityRequest<T>, WireError>

Convert a wire request back into a typed request.

Calls WirePayload::from_wire_bytes.

Errors

Returns WireError if deserialisation fails.

Trait Implementations

impl<T: Clone> Clone for CapabilityRequest<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for CapabilityRequest<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
