Enum BootstrapOverrideLld 

pub enum BootstrapOverrideLld {
    None,
    SelfContained,
    External,
}

Determines if we should override the linker used for linking Rust code built during the bootstrapping process to be LLD.

The primary use-case for this is to make local (re)builds of Rust code faster when using bootstrap.

This does not affect the behavior of the built/distributed compiler when invoked outside of bootstrap. It might affect its performance/binary size though, as that can depend on the linker that links rustc.

There are two ways of overriding the linker to be LLD:

• Self-contained LLD: use rust-lld from the compiler’s sysroot
• External: use an external lld binary

It is configured depending on the target:

1. Everything except MSVC

• Self-contained: -Clinker-features=+lld -Clink-self-contained=+linker
• External: -Clinker-features=+lld

2. MSVC

• Self-contained: -Clinker=<path to rust-lld>
• External: -Clinker=lld

Variants

None

Do not override the linker LLD

SelfContained

Use rust-lld from the compiler’s sysroot

External

Use an externally provided lld binary. Note that the linker name cannot be overridden, the binary has to be named lld and it has to be in $PATH.

Implementations

impl BootstrapOverrideLld

pub fn is_used(&self) -> bool

Trait Implementations

impl Clone for BootstrapOverrideLld

fn clone(&self) -> BootstrapOverrideLld

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BootstrapOverrideLld

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

Formats the value using the given formatter.

impl Default for BootstrapOverrideLld

fn default() -> BootstrapOverrideLld

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BootstrapOverrideLld

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BootstrapOverrideLld

fn eq(&self, other: &BootstrapOverrideLld) -> 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 Copy for BootstrapOverrideLld

impl StructuralPartialEq for BootstrapOverrideLld

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.
