Expand description

Internal fields of Unit which Unit will dereference to.

Fields§

§pkg: Package

Information about available targets, which files to include/exclude, etc. Basically stuff in Cargo.toml.

§target: Target

Information about the specific target to build, out of the possible targets in pkg. Not to be confused with target-triple (or target architecture …), the target arch for a build.

§profile: Profile

The profile contains information about how the build should be run, including debug level, etc.

§kind: CompileKind

Whether this compilation unit is for the host or target architecture.

For example, when cross compiling and using a custom build script, the build script needs to be compiled for the host architecture so the host rustc can use it (when compiling to the target architecture).

§mode: CompileMode

The “mode” this unit is being compiled for. See CompileMode for more details.

§features: Vec<InternedString>

The cfg features to enable for this unit. This must be sorted.

§artifact: IsArtifact§is_std: bool

Whether this is a standard library unit.

§dep_hash: u64

A hash of all dependencies of this unit.

This is used to keep the Unit unique in the situation where two otherwise identical units need to link to different dependencies. This can happen, for example, when there are shared dependencies that need to be built with different features between normal and build dependencies. See rebuild_unit_graph_shared for more on why this is done.

This value initially starts as 0, and then is filled in via a second-pass after all the unit dependencies have been computed.

§artifact_target_for_features: Option<CompileTarget>

This is used for target-dependent feature resolution and is copied from FeaturesFor::ArtifactDep, if the enum matches the variant.

Implementations§

source§

impl UnitInner

source

pub fn requires_upstream_objects(&self) -> bool

Returns whether compilation of this unit requires all upstream artifacts to be available.

This effectively means that this unit is a synchronization point (if the return value is true) that all previously pipelined units need to finish in their entirety before this one is started.

source

pub fn is_local(&self) -> bool

Returns whether or not this is a “local” package.

A “local” package is one that the user can likely edit, or otherwise wants warnings, etc.

source

pub fn show_warnings(&self, config: &Config) -> bool

Returns whether or not warnings should be displayed for this unit.
