# rustflags_debuginfo: default verbosity of debug information
#
# It corresponds to the "-Cdebuginfo" rustc command line option.
# In some cases, it might be required to override this macro with "1" or even
# "0", if memory usage gets too high during builds on some resource-constrained
# architectures (most likely on 32-bit architectures), which will however
# reduce the quality of the produced debug symbols.

#
# The default value of "1" results in generation of better code, but comes at
# the cost of longer build times.

# build_rustflags: default compiler flags for rustc (RUSTFLAGS)
#
# -Copt-level: set optimization level (default: highest optimization level)
# -Cdebuginfo: set debuginfo verbosity (default: full debug information)
# -Ccodegen-units: set number of parallel code generation units (default: 1)
# -Cforce-frame-pointers: force inclusion of frame pointers (default: enabled
#       on x86_64 and aarch64 on Fedora 37+)
