Remove the path.lib parameter that is substituted into the output
Cargo.toml by autoconf. Instead, as part of the build, "cd" into the
source directory. We already set the Rust target directory to the
external build directory.
This makes the Cargo.toml more generic, and in a format suitable for
publishing to crates.io. It also makes it easier to pull in external
crates without needing to patch up their Cargo.toml, for example, it
might make pulling libhtp-rs easier.
When deriving AppLayerEvent, allow the event name to be set with the
"name" attribute in cases where the transformed name is not suitable.
This allows us to use enum variant names like
"FtpEventRequestCommandTooLong" for direct use in C, but is also a
name that doesn't transform well to an event name in rules, where we
want to see "request_command_too_long".
The macro was generating code that references names use the "crate"
prefix which will fail if the macro is used by a library user or plugin.
Dynamically check where we are running an use the correct import paths
as needed.
Add generation of wrapper functions for get_event_info
and get_event_info_by_id to the derive macro. Eliminates
the need for the wrapper method to be created by the parser
author.
Currently has one derive, AppLayerEvent to be used like:
#[derive(AppLayerEvent)]
pub enum DNSEvent {
MalformedData,
NotRequest,
NotResponse,
ZFlagSet,
}
Code will be generated to:
- Convert enum to a c type string
- Convert string to enum variant
- Convert id to enum variant
