Fields§

§start: Instant

When Cargo started.

§start_str: &'a str

A rendered string of when compilation started.

§root_units: &'a [(String, Vec<String>)]

A summary of the root units.

Tuples of (package_description, target_descriptions).

§profile: &'a str

The build profile.

§total_fresh: u32

Total number of fresh units.

§total_dirty: u32

Total number of dirty units.

§unit_times: &'a [UnitTime]

Time tracking for each individual unit.

§concurrency: &'a [Concurrency]

Concurrency-tracking information. This is periodically updated while compilation progresses.

§cpu_usage: &'a [(f64, f64)]

Recorded CPU states, stored as tuples. First element is when the recording was taken and second element is percentage usage of the system.

§rustc_version: &'a str

Compiler version info, i.e., rustc 1.92.0-beta.2 (0a411606e 2025-10-31).

§host: &'a str

The host triple (arch-platform-OS).

§requested_targets: &'a [&'a str]

The requested target platforms of compilation for this build.

§jobs: u32

The number of jobs specified for this build.

§error: &'a Option<Error>

Fatal error during the build.

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.
