can we somehow infer this from matrix.os? maybe using uname or something?

Not sure if we need to specify those... If we don't, surely ${{ }} expressions referencing those fields will fail?

Yeah, I don't think we need to specify this. Can't say for sure though.

Alternatively, we can get rid of calling rustc to set target_os and target_arch, and specify the values for both statically in the config.

source rustc.vars

pushd target/release
else
# cross build with the specified rustc target
export target_os=${CROSS_COMPILE_OS}
export target_arch=${CROSS_COMPILE_TARGET}

pushd target/${CROSS_COMPILE_TARGET}/release
fi

pushd target/release

export ASSET_NAME="xsnippet-api-${target_arch}-${target_os}.exe.7z"
