Struct bootstrap::builder::Rustflags

struct Rustflags(String, TargetSelection);

Represents flag values in String form with whitespace delimiter to pass it to the compiler later.

-Z crate-attr flags will be applied recursively on the target code using the rustc_parse::parser::Parser. See rustc_builtin_macros::cmdline_attrs::inject for more information.

Tuple Fields

0: String

1: TargetSelection

Implementations

impl Rustflags

fn new(target: TargetSelection) -> Rustflags

fn propagate_cargo_env(&mut self, prefix: &str)

By default, cargo will pick up on various variables in the environment. However, bootstrap reuses those variables to pass additional flags to rustdoc, so by default they get overridden. Explicitly add back any previous value in the environment.

prefix is usually RUSTFLAGS or RUSTDOCFLAGS.

fn env(&mut self, env: &str)

fn arg(&mut self, arg: &str) -> &mut Self

Trait Implementations

impl Clone for Rustflags

fn clone(&self) -> Rustflags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rustflags

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

Formats the value using the given formatter.

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.
