Expand description

A structure returning the result of a compilation.

## Fields§

§`tests: Vec<UnitOutput>`

An array of all tests created during this compilation.

§`binaries: Vec<UnitOutput>`

An array of all binaries created.

§`cdylibs: Vec<UnitOutput>`

An array of all cdylibs created.

§`root_crate_names: Vec<String>`

The crate names of the root units specified on the command-line.

§`native_dirs: BTreeSet<PathBuf>`

All directories for the output of native build commands.

This is currently used to drive some entries which are added to the `LD_LIBRARY_PATH` as appropriate.

The order should be deterministic.

§`root_output: HashMap<CompileKind, PathBuf>`

Root output directory (for the local package’s artifacts)

§`deps_output: HashMap<CompileKind, PathBuf>`

Output directory for rust dependencies. May be for the host or for a specific target.

§`sysroot_target_libdir: HashMap<CompileKind, PathBuf>`

The path to libstd for each target

§`extra_env: HashMap<UnitHash, Vec<(String, String)>>`

Extra environment variables that were passed to compilations and should be passed to future invocations of programs.

The key is the build script metadata for uniquely identifying the `RunCustomBuild` unit that generated these env vars.

§`to_doc_test: Vec<Doctest>`

Libraries to test with rustdoc.

§`host: String`

The target host triple.

§`gctx: &'gctx GlobalContext`§`rustc_process: ProcessBuilder`

Rustc process to be used by default

§`rustc_workspace_wrapper_process: ProcessBuilder`

Rustc process to be used for workspace crates instead of `rustc_process`

§`primary_rustc_process: Option<ProcessBuilder>`

Optional rustc process to be used for primary crates instead of either `rustc_process` or `rustc_workspace_wrapper_process`

§`target_runners: HashMap<CompileKind, Option<(PathBuf, Vec<String>)>>`§`target_linkers: HashMap<CompileKind, Option<PathBuf>>`

The linker to use for each host or target.

§`warning_count: usize`

The total number of warnings emitted by the compilation.

## Implementations§

Source§

### impl<'gctx> Compilation<'gctx>

Source

#### pub fn new<'a>(bcx: &BuildContext<'a, 'gctx>) -> CargoResult<Compilation<'gctx>>

Source

#### pub fn rustc_process( &self, unit: &Unit, is_primary: bool, is_workspace: bool, ) -> CargoResult<ProcessBuilder>

Returns a `ProcessBuilder` for running `rustc`.

`is_primary` is true if this is a “primary package”, which means it was selected by the user on the command-line (such as with a `-p` flag), see `crate::core::compiler::BuildRunner::primary_packages`.

`is_workspace` is true if this is a workspace member.

Source

#### pub fn rustdoc_process( &self, unit: &Unit, script_metas: Option<&Vec<UnitHash>>, ) -> CargoResult<ProcessBuilder>

Returns a `ProcessBuilder` for running `rustdoc`.

Source

#### pub fn host_process<T: AsRef<OsStr>>( &self, cmd: T, pkg: &Package, ) -> CargoResult<ProcessBuilder>

Returns a `ProcessBuilder` appropriate for running a process for the host platform.

This is currently only used for running build scripts. If you use this for anything else, please be extra careful on how environment variables are set!

Source

#### pub fn target_runner( &self, kind: CompileKind, ) -> Option<&(PathBuf, Vec<String>)>

Source

#### pub fn target_linker(&self, kind: CompileKind) -> Option<PathBuf>

Gets the user-specified linker for a particular host or target.

Source

#### pub fn target_process<T: AsRef<OsStr>>( &self, cmd: T, kind: CompileKind, pkg: &Package, script_metas: Option<&Vec<UnitHash>>, ) -> CargoResult<ProcessBuilder>

Returns a `ProcessBuilder` appropriate for running a process for the target platform. This is typically used for `cargo run` and `cargo test`.

`script_metas` is the metadata for the `RunCustomBuild` unit that this unit used for its build script. Use `None` if the package did not have a build script.

Source

#### fn fill_env( &self, cmd: ProcessBuilder, pkg: &Package, script_metas: Option<&Vec<UnitHash>>, kind: CompileKind, tool_kind: ToolKind, ) -> CargoResult<ProcessBuilder>

Prepares a new process with an appropriate environment to run against the artifacts produced by the build process.

The package argument is also used to configure environment variables as well as the working directory of the child process.

## 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.
