Enum rustc_target::spec::LinkSelfContainedDefault

pub enum LinkSelfContainedDefault {
    True,
    False,
    InferredForMusl,
    InferredForMingw,
    WithComponents(LinkSelfContainedComponents),
}
Expand description

The different -Clink-self-contained options that can be specified in a target spec:

  • enabling or disabling in bulk
  • some target-specific pieces of inference to determine whether to use self-contained linking if -Clink-self-contained is not specified explicitly (e.g. on musl/mingw)
  • explicitly enabling some of the self-contained linking components, e.g. the linker component to use rust-lld

Variants§

§

True

The target spec explicitly enables self-contained linking.

§

False

The target spec explicitly disables self-contained linking.

§

InferredForMusl

The target spec requests that the self-contained mode is inferred, in the context of musl.

§

InferredForMingw

The target spec requests that the self-contained mode is inferred, in the context of mingw.

§

WithComponents(LinkSelfContainedComponents)

The target spec explicitly enables a list of self-contained linking components: e.g. for targets opting into a subset of components like the CLI’s -C link-self-contained=+linker.

Implementations§

source§

impl LinkSelfContainedDefault

source

pub fn is_disabled(self) -> bool

Returns whether the target spec has self-contained linking explicitly disabled. Used to emit errors if the user then enables it on the CLI.

source

pub fn is_linker_enabled(self) -> bool

Returns whether the target spec explicitly requests self-contained linking, i.e. not via inference.

source

fn json_key(self) -> &'static str

Returns the key to use when serializing the setting to json:

  • individual components in a link-self-contained object value
  • the other variants as a backwards-compatible crt-objects-fallback string
