ndk-macro

Implementation of the attribute procedural macro main which applied directly to main function.

This macro is re-exported in ndk-glue. Typically, it's not needed to depend on this library directly!

Usage

#[cfg_attr(target_os = "android", ndk_glue::main(backtrace = "on"))]
pub fn main() {
    println!("hello world");
}

The attribute macro supports optional input attributes:

• backtrace = "on|full": Enables backtraces by setting the RUST_BACKTRACE env var
• ndk_glue = "path::to::ndk_glue": Overrides default path to ndk_glue crate
• logger(...props): Configures android logger with the passed configuration (requires the logger feature):
  • level = "error|warn|info|debug|trace": Changes log level for logger
  • tag = "my-tag": Assigns tag to logger
  • filter = "filtering-rules": Changes default filtering rules
