Configuring the Cargo.toml file to add crates

Chromium has a single set of centrally-managed direct crate dependencies. These are managed through a single Cargo.toml:

bitflags = "1"
cfg-if = "1"
cxx = "1"
# lots more...

As with any other Cargo.toml, you can specify more details about the dependencies — most commonly, you’ll want to specify the features that you wish to enable in the crate.

When adding a crate to Chromium, you’ll often need to provide some extra information in an additional file, gnrt_config.toml, which we’ll meet next.
