# Rust's standard distribution of crates and tools
|
|
#
|
|
# The crates outlined below are the standard distribution of libraries provided
|
|
# in a rust installation. These rules are meant to abstract over the
|
|
# dependencies (both native and rust) of crates and basically generate all the
|
|
# necessary makefile rules necessary to build everything.
|
|
#
|
|
# Here's an explanation of the variables below
|
|
#
|
|
# TARGET_CRATES
|
|
# This list of crates will be built for all targets, including
|
|
# cross-compiled targets
|
|
#
|
|
# HOST_CRATES
|
|
# This list of crates will be compiled for only host targets. Note that
|
|
# this set is explicitly *not* a subset of TARGET_CRATES, but rather it is
|
|
# a disjoint set. Nothing in the TARGET_CRATES set can depend on crates in
|
|
# the HOST_CRATES set, but the HOST_CRATES set can depend on target
|
|
# crates.
|
|
#
|
|
# TOOLS
|
|
# A list of all tools which will be built as part of the compilation
|
|
# process. It is currently assumed that most tools are built through
|
|
# src/driver/driver.rs with a particular configuration (there's a
|
|
# corresponding library providing the implementation)
|
|
#
|
|
# DEPS_<crate>
|
|
# These lists are the dependencies of the <crate> that is to be built.
|
|
# Rust dependencies are listed bare (i.e. std, extra, green) and native
|
|
# dependencies have a "native:" prefix (i.e. native:sundown). All deps
|
|
# will be built before the crate itself is built.
|
|
#
|
|
# TOOL_DEPS_<tool>/TOOL_SOURCE_<tool>
|
|
# Similar to the DEPS variable, this is the library crate dependencies
|
|
# list for tool as well as the source file for the specified tool
|
|
#
|
|
# You shouldn't need to modify much other than these variables. Crates are
|
|
# automatically generated for all stage/host/target combinations.
