Struct CrateHeader 

pub(crate) struct CrateHeader {
    pub(crate) triple: TargetTuple,
    pub(crate) hash: Svh,
    pub(crate) name: Symbol,
    pub(crate) is_proc_macro_crate: bool,
    pub(crate) is_stub: bool,
}

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: TargetTuple

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.

is_stub: bool

Whether this crate metadata section is just a stub. Stubs do not contain the full metadata (it will be typically stored in a separate rmeta file).

This is used inside rlibs and dylibs when using -Zembed-metadata=no.

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.
