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
- android_logger = "path::to::android_logger": Overrides default path to android_logger crate
- log = "path::to::log": Overrides default path to log crate
