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.

## 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.
