Struct NullCodecResolver 

pub struct NullCodecResolver;

Null resolver that resolves nothing — useful as a default when a caller doesn’t have a real registry handy (e.g. unit tests, or legacy callers of the tag-free open() APIs).

Trait Implementations

impl Clone for NullCodecResolver

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CodecResolver for NullCodecResolver

fn resolve_tag(&self, _ctx: &ProbeContext<'_>) -> Option<CodecId>

Resolve the tag in ctx.tag to a codec id. Implementations walk every registration whose tag set contains the tag, call each probe (treating None as “always 1.0”), and return the id with the highest resulting confidence. Ties are broken by registration order.

fn resolve_payload_magic(&self, first_bytes: &[u8]) -> Option<CodecId>

Resolve a codec from a stream’s leading payload bytes, for carriage formats that announce the codec in the payload itself rather than through a container tag.

impl Copy for NullCodecResolver

impl Default for NullCodecResolver

fn default() -> Self

Returns the “default value” for a type.
