class StringView

Defined at line 23 of file ../../sdk/lib/fidl/cpp/wire/include/lib/fidl/cpp/wire/string_view.h

A FIDL string that borrows its contents.

StringView instances can be passed by value, as copying is cheap.

void StringView (T (&)[N] literal)

Disable `explicit` requirements because we want implicit conversions from string literals.

StringView FromExternal (std::string_view from)

Constructs a fidl::StringView by unsafely borrowing other strings.

These methods are the only way to reference data which is not managed by an |Arena|.

Their usage is discouraged. The lifetime of the referenced string must be longer than the

lifetime of the created StringView.

For example:

std::string foo = path + "/foo";

auto foo_view = fidl::StringView::FromExternal(foo);

char name[kLength];

snprintf(name, sizeof(name), "Hello %d", 123);

auto name_view = fidl::StringView::FromExternal(name);
