pub struct LinkSelfContained {
    pub explicitly_set: Option<bool>,
    components: LinkSelfContainedComponents,
}
Expand description

The different values -C link-self-contained can take: a list of individually enabled or disabled components used during linking, coming from the rustc distribution, instead of being found somewhere on the host system.

They can be set in bulk via -C link-self-contained=yes|y|on or -C link-self-contained=no|n|off, and those boolean values are the historical defaults.

But each component is fine-grained, and can be unstably targeted, to use:

  • some CRT objects
  • the libc static library
  • libgcc/libunwind libraries
  • a linker we distribute
  • some sanitizer runtime libraries
  • all other MinGW libraries and Windows import libs

Fields§

§explicitly_set: Option<bool>

Whether the user explicitly set -C link-self-contained on or off, the historical values. Used for compatibility with the existing opt-in and target inference.

§components: LinkSelfContainedComponents

The components that are enabled.

Implementations§

source§

impl LinkSelfContained

source

pub(crate) fn handle_cli_component(&mut self, component: &str) -> Result<(), ()>

Incorporates an enabled or disabled component as specified on the CLI, if possible. For example: +linker, and -crto.

source

pub(crate) fn set_all_explicitly(&mut self, enabled: bool)

Turns all components on or off and records that this was done explicitly for compatibility purposes.

source

pub fn on() -> Self

Helper creating a fully enabled LinkSelfContained instance. Used in tests.

source

fn are_unstable_variants_set(&self) -> bool

To help checking CLI usage while some of the values are unstable: returns whether one of the components was set individually. This would also require the -Zunstable-options flag, to be allowed.

source

pub fn linker(&self) -> bool

Returns whether the self-contained linker component is enabled.
