Struct ValueCodecRegistration 

pub struct ValueCodecRegistration<D: 'static> { /* private fields */ }

One statically linked value-codec implementation.

A registration bundles the stable identifier used for lookup and duplicate detection, a borrowed executable descriptor, and the link-time location the registration was declared at. It is produced by register_value_string_codec! or register_value_bytes_codec! rather than built by hand.

Type Parameters

• D: Executable codec descriptor type; 'static lets the registry keep a borrowed &'static D for the whole program run.

Examples

use qubit_codec::JsonStringValueCodec;
use qubit_codec::ValueCodecId;
use qubit_codec::ValueCodecRegistration;
use qubit_codec::ValueCodecRegistrationSource;
use qubit_codec::ValueStringCodecDescriptor;
use qubit_codec::ValueStringCodecRegistration;

static DESCRIPTOR: ValueStringCodecDescriptor =
    ValueStringCodecDescriptor::of::<JsonStringValueCodec<u32>, u32>();

let registration: ValueStringCodecRegistration = ValueCodecRegistration::new(
    ValueCodecId::new("example.u32"),
    &DESCRIPTOR,
    ValueCodecRegistrationSource::new(
        "qubit-codec",
        "doctest",
        "src/value/value_codec_registration.rs",
        1,
    ),
);
assert_eq!(registration.id().as_str(), "example.u32");

Implementations

impl<D: 'static> ValueCodecRegistration<D>

pub const fn id(&self) -> ValueCodecId

Returns the stable value-codec ID.

Returns

Returns the identifier this registration was filed under.

pub const fn descriptor(&self) -> &'static D

Returns the executable descriptor.

Returns

Returns the borrowed static descriptor, valid for the whole program run.

pub const fn source(&self) -> ValueCodecRegistrationSource

Returns the linked source location.

Returns

Returns the link-time crate, module, file, and line of the declaration.
