Struct UWireMetadataContext

pub struct UWireMetadataContext {
    pub wire_id: WireIdentity,
    pub payload_family_id: WireIdentity,
    pub metadata_layout_id: WireIdentity,
    pub format_version: u16,
    /* private fields */
}

Selected-wire metadata context consumed by metadata codecs.

Fields

wire_id: WireIdentity

Stable identity for the full selected wire.

payload_family_id: WireIdentity

Payload operation family supported by this selected wire.

metadata_layout_id: WireIdentity

Metadata byte layout used by this selected wire.

format_version: u16

Metadata byte-format version supported by this selected wire.

Implementations

impl UWireMetadataContext

pub fn from_wire<W>() -> Self

where W: UWire,

Builds a metadata context for a selected wire marker type.

pub fn new_exact( wire_id: WireIdentity, payload_family_id: WireIdentity, metadata_layout_id: WireIdentity, format_version: u16, ) -> Self

Builds a metadata context with exact identity matching.

pub fn with_metadata_layout(self, metadata_layout_id: WireIdentity) -> Self

Returns this context with the metadata layout identity replaced.

Metadata codecs overlay their own profile identity so the layout id on the wire always names the codec’s byte profile, independent of the legacy per-wire declaration.

pub fn wire_compatibility(&self, actual: &WireIdentityRef) -> WireCompatibility

Checks selected-wire compatibility before public frame exposure.

pub fn payload_family_compatibility( &self, actual: &WireIdentityRef, ) -> WireCompatibility

Checks payload-family compatibility before public frame exposure.

Trait Implementations

impl Clone for UWireMetadataContext

fn clone(&self) -> UWireMetadataContext

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

Performs copy-assignment from source.

impl Debug for UWireMetadataContext

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