Subject: rust/bindgen: use temp file to generating bindings
X-Git-Tag: suricata-8.0.0-beta1~385
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cdb87953859d03f6108826bb168c00b88d135f8;p=thirdparty%2Fsuricata.git

rust/bindgen: use temp file to generating bindings

Prefixing a file with sed doesn't appear to be portable. Instead, make
use of a temporary file.

Fixes generating the bindings on FreeBSD and Mac.
