guppy-summaries

guppy-summaries on crates.io Documentation (latest release) Documentation (main) License License

Facilities to serialize, deserialize and compare build summaries.

A build summary is a record of what packages and features are built on the target and host platforms. A summary file can be checked into a repository, kept up to date and compared in CI, and allow for tracking results of builds over time.

guppy-summaries is designed to be small and independent of the main guppy crate.

Examples

use guppy_summaries::{Summary, SummaryId, SummarySource, PackageStatus};
use pretty_assertions::assert_eq;
use semver::Version;
use std::collections::BTreeSet;
use toml::Value;

// A summary is a TOML file that has this format:
static SUMMARY: &str = r#"
[[target-package]]
name = "foo"
version = "1.2.3"
workspace-path = "foo"
status = 'initial'
features = ["feature-a", "feature-c"]

[[host-package]]
name = "proc-macro"
version = "0.1.2"
workspace-path = "proc-macros/macro"
status = 'workspace'
features = ["macro-expand"]

[[host-package]]
name = "bar"
version = "0.4.5"
crates-io = true
status = 'direct'
features = []
"#;

// The summary can be deserialized:
let summary = Summary::parse(SUMMARY).expect("from_str succeeded");

// ... and a package and its features can be looked up.
let summary_id = SummaryId::new("foo", Version::new(1, 2, 3), SummarySource::workspace("foo"));
let info = &summary.target_packages[&summary_id];
assert_eq!(info.status, PackageStatus::Initial, "correct status");
assert_eq!(
    info.features.iter().map(|feature| feature.as_str()).collect::<Vec<_>>(),
    ["feature-a", "feature-c"],
    "correct feature list"
);

// Another summary.
static SUMMARY2: &str = r#"
[[target-package]]
name = "foo"
version = "1.2.4"
workspace-path = "new-location/foo"
status = 'initial'
features = ["feature-a", "feature-b"]

[[target-package]]
