Struct rustc_session::config::ExternEntry

pub struct ExternEntry {
    pub location: ExternLocation,
    pub is_private_dep: bool,
    pub add_prelude: bool,
    pub nounused_dep: bool,
    pub force: bool,
}

Fields

location: ExternLocation

is_private_dep: bool

Indicates this is a “private” dependency for the exported_private_dependencies lint.

This can be set with the priv option like --extern priv:name=foo.rlib.

add_prelude: bool

Add the extern entry to the extern prelude.

This can be disabled with the noprelude option like --extern noprelude:name.

nounused_dep: bool

The extern entry shouldn’t be considered for unused dependency warnings.

--extern nounused:std=/path/to/lib/libstd.rlib. This is used to suppress unused-crate-dependencies warnings.

force: bool

If the extern entry is not referenced in the crate, force it to be resolved anyway.

Allows a dependency satisfying, for instance, a missing panic handler to be injected without modifying source: --extern force:extras=/path/to/lib/libstd.rlib

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.
