Struct rustc_metadata::rmeta::decoder::MetadataBlob

pub(crate) struct MetadataBlob(Lrc<MetadataRef>);

A reference to the raw binary version of crate metadata. A MetadataBlob internally is just a reference counted pointer to the actual data, so cloning it is cheap.

Tuple Fields

0: Lrc<MetadataRef>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
