%description
Rust is a systems programming language that runs blazingly fast, prevents
segfaults, and guarantees thread safety.

This package includes the Rust compiler, standard library, and documentation
generator.


%package gdb
Summary:        GDB pretty printers for Rust
BuildArch:      noarch
Requires:       gdb

%description gdb
This package includes the rust-gdb script, which allows easier debugging of Rust
programs.


%package doc
Summary:        Documentation for Rust
# NOT BuildArch:      noarch
# Note, while docs are mostly noarch, some things do vary by target_arch.
# Koji will fail the build in rpmdiff if two architectures build a noarch
# subpackage differently, so instead we have to keep its arch.

%description doc
This package includes HTML documentation for the Rust programming language and
its standard library.


# TODO: consider a rust-std package containing .../rustlib/$target
# This might allow multilib cross-compilation to work naturally.
