Classes
struct	Device
	The device facts a can_run predicate and the table lookup read (§5.1). More...
struct	FamilyName
	A string literal as a template argument: the name of a NoFields family. More...
struct	NoFields
	Base of a family with no knobs: struct Cta : NoFields<"cta"> {};. More...
struct	overloaded
	std::visit over a choice with one lambda per family. More...
struct	Rules
	What an op adds to the generic walk: its last-resort order. More...
struct	KeyField
	One field of a lookup key, value as text; a Key lists the fields an op's table keys name. More...
struct	TableKey
	One entry of a table's # keys: line. More...
struct	TableEntry
	One ranked candidate of a row: its spelling and milliseconds per call for the whole batch. More...
struct	TableRow
	One measured (or transcribed) shape and every candidate ranked there, fastest first. More...
struct	Table
	One dtype's table: a tuned/<op>.<device>.txt file holds one per dtype. More...
struct	EmbeddedTable
	A tuned/*.txt file compiled into the library: its basename and text. More...
struct	StrictPin
	Tag for a strict ScopedPin: a class word ("native", "vendor") that cannot serve the shape throws std::invalid_argument instead of falling back to auto. More...
class	ScopedPin
	RAII pin for op: wins over BATCHLAS_<OP>_ROUTE on this thread; nests, restoring the outer pin on exit. More...
class	TraceScope
	Prints the last choose() decision for op under BATCHLAS_SELECT_TRACE=1, indents nested scopes, and records the coverage row. More...
struct	OpSpec
	What an op's choice.hh declares once: its name, the library its Vendor family calls (one gate for can_run, the launch arm and the NoRouteError), and its last-resort order. More...
struct	NativeFacts
	The coverage row's native_route_existed / native_route_supported (tri-state, -1 unknown). More...
