{{/*
	For FIDL tracing, the Rust bindings are assigned a bindings enum of 6. See
	fidl-trace/trace_impl.cc, enum LogContext for more context.

	This constant will be unused in a build that has FIDL tracing disabled,
	since this constant is used only within trace_duration! macros that will
	expand to no-ops. However, the constant needs to be present, since the
	constant is evaluated before the macro expansion.

	The constant starts with an underscore to avoid clashing with FIDL
	declarations, which are not allowed to start with underscores.
