Struct NullCodecResolver

pub struct NullCodecResolver;

Expand description

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) -> NullCodecResolver

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

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.

impl Default for NullCodecResolver

fn default() -> NullCodecResolver

Returns the “default value” for a type. Read more

impl Copy for NullCodecResolver
