This commit is the initial steps to migrate Cargo's error handling from the `error-chain` crate to the `failure` crate. This is intended to be a low-cost (in terms of diff) transition where possible so it's note "purely idiomatic `failure` crate" just yet. The `error-chain` dependency is dropped in this commit and Cargo now canonically uses the `Error` type from the `failure` crate. The main last remnant of `error-chain` is a custom local extension trait to use `chain_err` instead of `with_context`. I'll try to follow up with a commit that renames this later but I wanted to make sure everything worked first! (and `chain_err` is used practically everywhere). Some minor tweaks happened in the tests as I touched up a few error messages here and there but overall the UI of Cargo should be exactly the same before and after this commit.

Manage the owners of a crate on the registry
|
|
|
|
Usage:
|
|
cargo owner [options] [<crate>]
|
|
|
|
Options:
|
|
-h, --help Print this message
|
|
-a, --add LOGIN Name of a user or team to add as an owner
|
|
-r, --remove LOGIN Name of a user or team to remove as an owner
|
|
-l, --list List owners of a crate
|
|
--index INDEX Registry index to modify owners for
|
|
--token TOKEN API token to use when authenticating
|
|
-v, --verbose ... Use verbose output (-vv very verbose/build.rs output)
|
|
-q, --quiet No output printed to stdout
|
|
--color WHEN Coloring: auto, always, never
|
|
--frozen Require Cargo.lock and cache are up to date
|
|
--locked Require Cargo.lock is up to date
|
|
-Z FLAG ... Unstable (nightly-only) flags to Cargo
|
|
--registry REGISTRY Registry to use
|
|
|
|
This command will modify the owners for a package on the specified registry (or
|
|
default). Note that owners of a package can upload new versions, yank old
|
|
versions. Explicitly named owners can also modify the set of owners, so take
|
|
caution!
|
|
|
|
See http://doc.crates.io/crates-io.html#cargo-owner for detailed documentation
|
|
and troubleshooting.
