Trait Logger 

pub trait Logger: Send {
    // Required methods
    fn log_debug(&self, log_line: String);
    fn log_error(&self, log_line: String);
    fn log_info(&self, log_line: String);
    fn log_trace(&self, log_line: String);
    fn log_warn(&self, log_line: String);
}

Trait that can be used to forward Rust logs over FFI to a language specific logger.

FFI return type for trait interfaces

fn try_lift_successful_return(v: Self::ReturnType) -> Result<Self>

Lift a successfully returned value from a trait interface

fn lift_foreign_return( ffi_return: Self::ReturnType, call_status: RustCallStatus, ) -> Self

Lift a foreign returned value from a trait interface

fn lift_error(_buf: RustBuffer) -> Self

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
