To replace my car on the daily school run, I need an electrically powered workhorse that will carry two smallish children and the bags of stuff that we lug around wherever we go.
But I’m returning to cycling because I want to take my children to school and nursery without the horrible sense of guilt from dropping them off in the car, complaints about walking or the juggle of pushchair and public transport at rush-hour. Which is generally for documenting user-facing The Cargo Book,īut the Cargo team is welcome any form of enhancement for the Cargo Contributor GuideĪnd this API documentation as well.It’s been 20 years since I last used a bike every day. There is also an issue label A-documenting-cargo-itself, Zulip t-cargo stream, or submit an issue right on GitHub. If you spot anything could be better, don’t hesitate to discuss with the team on The Cargo team always continues improving all external and internal documentations.
Cargo rust download#
index/: Fast-to-access crate metadata (no need to download / extract *.crate files).Be carefulĪs the lock util::Config::acquire_package_cache_lock must be manually acquired. registry/: Package registry cache which is managed in sources::registry.target/debug/.fingerprint: Tracker whether nor not a crate needs to be rebuilt.There is a separate Layout for each build target. Layout handles locking the target directory and providing paths to parts inside. target/: Used for build artifacts and abstracted with core::compiler::layout.See core::resolver::encode for versioning of Cargo.lock.At the lowest level, ops::load_pkg_lockfile and ops::write_pkg_lockfile are used.Cargo.lock: Generally loaded with ops::resolve_ws or a variant of it into a core::resolver::Resolve.This is editable with util::toml_mut::manifest::LocalManifest.Translated to core::manifest::Manifest which maybe stored in a core::Package. Cargo.toml: User-written project manifest, loaded with util::toml::TomlManifest and then.This is a dedicated package that defines tests for the dependency This is a utility for generating cargo’s man pages. This subdirectory contains several packages for implementing the This is the # proc-macro used by the test suite to define tests.
Cargo rust code#
This contains a variety of code to support writing tests
Cargo rust update#
Whenever a change needs to be made, bump the version in Cargo.toml and cargo publish it manually, and then update cargo’s Cargo.toml to depend on the new version. It is intended to be versioned and published independently of Rust’s release system. This is not directly depended upon with a path dependency cargo uses the version from crates.io. This library is shared between cargo and rustup and is used for finding their home directories. This contains code for accessing the crates.io API. This contains general utility code that is shared between cargo and the testsuite This library handles parsing cfg expressions. This is where Cargo.lock files are loaded and saved. This directory contains the code for parsing Cargo.toml files. Though references to it are scattered around for more convenient access. Util::Config is usually accessed from the Serde to merge and translate config values. This directory contains the config parser. This directory contains generally-useful utility modules. Sources are uniquely identified by a core::SourceId. The core::Source trait is an abstraction over different sources of packages. The fingerprint module contains all the code that handles detecting Is the core of the build process, and everything is coordinated through The Context is the mutable state used during the build process. After this is built, the next stage of building is handled in This contains the graph of work to perform and any settings necessary for The BuildContext is the result of the “front end” of theīuild process. This is the code responsible for running rustc and rustdoc. Top-level API for dependency and feature resolver (e.g. Good place to start if you want to follow how compilation starts and This is the entry point for all the compilation commands.
Each command is a thin wrapper around ops. OverviewĮvery major operation is implemented here. See The Cargo Book:Įxternal tools for more on this topic. WARNING: Using Cargo as a library has drawbacks, particulary the API is unstable,Īnd there is no clear path to stabilize it soon at the time of writing.
