Struct PrismLogHandler 

#[repr(C)]
pub struct PrismLogHandler {
    pub fn_: PrismLogCallback,
    pub userdata: *mut c_void,
}

A structure pairing a log callback with an opaque user pointer.

Fields

fn_: PrismLogCallback

The callback invoked to deliver messages, or NULL to install no handler. When fn is NULL, messages are discarded.

userdata: *mut c_void

An opaque pointer passed unmodified to fn on each invocation. Prism does not interpret or take ownership of this value. The lifetime of this value is the lifetime of the handler function, and therefore this value must be valid for as long as the handler is alive.
