Enum rustc_target::spec::LinkSelfContainedDefault

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

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

impl LinkSelfContainedDefault

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.

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

pub fn with_linker() -> LinkSelfContainedDefault

Creates a LinkSelfContainedDefault enabling the self-contained linker for target specs (the equivalent of -Clink-self-contained=+linker on the CLI).

Trait Implementations

impl Clone for LinkSelfContainedDefault

fn clone(&self) -> LinkSelfContainedDefault

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinkSelfContainedDefault

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for LinkSelfContainedDefault

Parses a backwards-compatible -Clink-self-contained option string, without components.

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<LinkSelfContainedDefault, ()>

Parses a string s to return a value of this type.

impl PartialEq for LinkSelfContainedDefault

fn eq(&self, other: &LinkSelfContainedDefault) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToJson for LinkSelfContainedDefault

fn to_json(&self) -> Json

impl Copy for LinkSelfContainedDefault

impl StructuralPartialEq for LinkSelfContainedDefault

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.
