template<typename Context>
class dynamic_format_arg_store< Context >
A dynamic list of formatting arguments with storage.
It can be implicitly converted into fmt::basic_format_args
for passing into type-erased formatting functions such as fmt::vformat
.
template<typename Context >
template<typename T >
Adds an argument into the dynamic store for later passing to a formatting function.
Note that custom types and string types (but not string views) are copied into the store dynamically allocating memory if necessary.
Example:
fmt::dynamic_format_arg_store<fmt::format_context> store;
store.push_back(42);
store.push_back("abc");
store.push_back(1.5f);
std::string result = fmt::vformat("{} and {} and {}", store);
