Struct CapturedRustcArtifact 

pub struct CapturedRustcArtifact {

    pub crate_name: String,
    pub crate_version: Option<String>,
    pub crate_types: Vec<String>,
    pub emit: Vec<String>,
    pub target: Option<String>,
    pub compile_key: String,
    pub c_metadata: String,
    pub extra_filename: String,
    pub dependencies: Vec<CapturedDependencyIdentity>,
    pub profile: Profile,
    pub out_dir: PathBuf,
    pub target_dir: PathBuf,

    pub restorable: bool,
    pub compile_millis: u64,
}

One rustc invocation the capture wrapper observed, recorded as it exited.

Every cargo unit routed through the wrapper produces a record — not only the ones whose outputs are restorable artifacts — so that a record forged inside the sandbox collides with the genuine one the wrapper sent. An invocation with no -C metadata is not a cargo unit (a build script or cargo itself probing rustc); it runs unrecorded, so an empty c_metadata arriving on the channel can only be a forgery.

Fields

crate_name: String

The --crate-name rustc was invoked with.

crate_version: Option<String>

The crate version this invocation actually compiled, read from the registry source path.

Recorded because a dependency graph can legitimately contain two versions of one crate (bitflags 1.3.2 alongside 2.5.0, say), and they share a library target name. Attributing captures by name alone let one version’s compiled bytes be registered under the other’s identity.

crate_types: Vec<String>

The --crate-type list rustc was invoked with.

emit: Vec<String>

The --emit list rustc was invoked with.

target: Option<String>

The --target triple rustc was invoked with, when cargo passed one.

compile_key: String

Full compile key of this invocation: the 64-hex blake3 stable identity for registry crates, or cargo’s ephemeral -C metadata for non-registry roots. c_metadata is its 16-hex stable prefix.

c_metadata: String

Cargo’s -C metadata for this invocation, or its stable prefix when the invocation was rewritten under a stable identity. Never empty in a genuine record.

extra_filename: String

Cargo’s -C extra-filename for this invocation.

dependencies: Vec<CapturedDependencyIdentity>

Resolved dependency identities for restorable units; always empty for observed ones (nothing downstream resolves their externs).

profile: Profile

The effective rustc profile (opt-level, debuginfo, …) of this invocation.

out_dir: PathBuf

Cargo’s --out-dir for this invocation; empty when the unit took none.

target_dir: PathBuf

The CARGO_TARGET_DIR the invocation ran under. The same unit is legitimately compiled once per cargo phase, and the phase’s target dir is what tells those records apart.

build_script_out_dir: Option<PathBuf>

Cargo’s OUT_DIR env for crates with a build script: the exact per-invocation build dir, recorded so native-artifact capture never has to guess which {crate}-{hash} directory belongs to this invocation.

outputs: Vec<CapturedRustcOutput>

The outputs rustc wrote, each with the digest taken as rustc exited.

restorable: bool

true when this unit’s outputs are artifacts the pipeline plans and publishes; false for cargo units that produce nothing publishable (build-script compiles, binaries, tests), which are recorded purely so a forged record has something to collide with.

compile_millis: u64

Wall-clock milliseconds the rustc invocation took — what a cache hit on this artifact saves a consumer. Records captured before the field existed carry no timing and count as zero.
