Struct rustc_metadata::rmeta::CrateHeader
source · pub(crate) struct CrateHeader {
pub(crate) triple: TargetTriple,
pub(crate) hash: Svh,
pub(crate) name: Symbol,
pub(crate) is_proc_macro_crate: bool,
}
Expand description
Serialized crate metadata.
This contains just enough information to determine if we should load the CrateRoot
or not.
Prefer CrateRoot
whenever possible to avoid ICEs when using omit-git-hash
locally.
See #76720 for more details.
If you do modify this struct, also bump the METADATA_VERSION
constant.
Fields§
§triple: TargetTriple
§hash: Svh
§name: Symbol
§is_proc_macro_crate: bool
Whether this is the header for a proc-macro crate.
This is separate from ProcMacroData
to avoid having to update METADATA_VERSION
every
time ProcMacroData changes.

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.
