Macro glib::error

macro_rules! error {
    (target : $target : expr, $($arg : tt) +) => { ... };
    ($($arg : tt) +) => { ... };
}

This is supported on crate feature log_macros only.

A macro which behaves exactly as log::error! except that it sets the current log target to the contents of a G_LOG_DOMAIN constant (and fails to build if not defined).

In order to use this macro, glib must be built with the log_macros feature enabled and the GlibLogger must have been initialized using GlibLoggerDomain::CrateTarget.

static G_LOG_DOMAIN: &str = "my-domain";

glib::error!("This will be logged under 'my-domain'");
