Struct rustc_session::config::LinkSelfContained
source · 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
impl LinkSelfContained
sourcepub(crate) fn handle_cli_component(&mut self, component: &str) -> Result<(), ()>
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
.
sourcepub(crate) fn set_all_explicitly(&mut self, enabled: bool)
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.
sourcefn are_unstable_variants_set(&self) -> bool
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.

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.
