Classes
struct	Halide::Error
	A base class for Halide errors. More...
struct	Halide::RuntimeError
	An error that occurs while running a JIT-compiled Halide pipeline. More...
struct	Halide::CompileError
	An error that occurs while compiling a Halide pipeline that Halide attributes to a user error. More...
struct	Halide::InternalError
	An error that occurs while compiling a Halide pipeline that Halide attributes to an internal compiler bug, or to an invalid use of Halide's internals. More...
class	Halide::CompileTimeErrorReporter
	CompileTimeErrorReporter is used at compile time (not runtime) when an error or warning is generated by Halide. More...
struct	Halide::Internal::ErrorReport
class	Halide::Internal::Voidifier

Namespaces
	Halide
	This file defines the class FunctionDAG, which is our representation of a Halide pipeline, and contains methods to using Halide's bounds tools to query properties of it.
	Halide::Internal

Macros

Macro Definition Documentation

_halide_internal_assertion

#define _halide_internal_assertion	(		condition,
			flags
	)

Value:

    /* NOLINTNEXTLINE(bugprone-macro-parentheses) */ \
    (condition) ? (void)0 : ::Halide::Internal::Voidifier() & ::Halide::Internal::ErrorReport(__FILE__, __LINE__, #condition, flags).ref()

_halide_internal_assertion is used to implement our assertion macros in such a way that the messages output for the assertion are only evaluated if the assertion's value is false.

Note that this macro intentionally has no parens internally; in actual use, the implicit grouping will end up being

condition ? (void) : (Voidifier() & (ErrorReport << arg1 << arg2 ... << argN))

This (regrettably) requires a macro to work, but has the highly desirable effect that all assertion parameters are totally skipped (not ever evaluated) when the assertion is true.
