// This library contains functions to assist dumping objects to stderr during
|
|
// interactive debugging. Functions named `Dump` are intended for direct use by
|
|
// developers, and should use overload resolution to determine which will be
|
|
// invoked. The debugger should do namespace resolution automatically. For
|
|
// example:
|
|
//
|
|
// - lldb: `expr Dump(context, id)`
|
|
// - gdb: `call Dump(context, id)`
|
|
//
|
|
// The `DumpNoNewline` functions are helpers that exclude a trailing newline.
|
|
// They're intended to be composed by `Dump` function implementations.
