Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

jobs: Option<i32>

Sets the maximum number of compiler processes to run in parallel. If negative, it sets the maximum number of compiler processes to the number of logical CPUs plus provided value. Should not be 0.

Cargo Reference

rustc: Option<PathBuf>

Sets the executable to use for rustc.

Cargo Reference

Note: If a wrapper is set, cargo’s actual rustc call goes through the wrapper, so you may want to use Config::rustc, which respects that behavior instead of referencing this value directly.

rustc_wrapper: Option<PathBuf>

Sets a wrapper to execute instead of rustc.

Cargo Reference

Note: If a wrapper is set, cargo’s actual rustc call goes through the wrapper, so you may want to use Config::rustc, which respects that behavior instead of referencing this value directly.

rustc_workspace_wrapper: Option<PathBuf>

Sets a wrapper to execute instead of rustc, for workspace members only.

Cargo Reference

Note: If a wrapper is set, cargo’s actual rustc call goes through the wrapper, so you may want to use Config::rustc, which respects that behavior instead of referencing this value directly.

rustdoc: Option<PathBuf>

Sets the executable to use for rustdoc.

Cargo Reference

target: Option<Vec<TargetTriple>>

The default target platform triples to compile to.

Cargo Reference

target_dir: Option<PathBuf>

The path to where all compiler output is placed. The default if not specified is a directory named target located at the root of the workspace.

Cargo Reference

build_dir: Option<PathBuf>

The path to where all compiler intermediate artifacts are placed. The default if not specified is the value of build.target-dir

Cargo Reference

Note: If a template variable is used the path will be unresolved. For available template variables see the Cargo reference.

rustflags: Option<Flags>

Extra command-line flags to pass to rustc. The value may be an array of strings or a space-separated string.

Cargo Reference

Note: This field does not reflect the target-specific rustflags configuration, so you may want to use Config::rustflags which respects the target-specific rustflags configuration.

rustdocflags: Option<Flags>

Extra command-line flags to pass to rustdoc. The value may be an array of strings or a space-separated string.

Cargo Reference

Note: This field does not reflect the target-specific rustdocflags configuration, so you may want to use Config::rustdocflags which respects the target-specific rustdocflags configuration.

incremental: Option<bool>

Whether or not to perform incremental compilation.

Cargo Reference

dep_info_basedir: Option<PathBuf>

Strips the given path prefix from dep info file paths.
