| Name| Description
| xref:BloombergLP/bslfmt/StreamedFormatter/format.adoc[`format`] 
| Format the specified `value` according to the specification stored as a result of a previous call to the `parse` method, and write the result to the iterator accessed by calling the `out()` method on the specified `formatContext` parameter. Return an end iterator of the output range. Throw an exception of type `bsl::format_error` in the event of failure.
| xref:BloombergLP/bslfmt/StreamedFormatter/parse.adoc[`parse`] 
| Parse and validate the specification string stored in the iterator accessed via the `begin()` method of the parseContext passed via the specified `parseContext` parameter. Where nested parameters are encountered in the specification string then the `next_arg_id` and `check_arg_id` are called on `fc` as specified in the C++ Standard. Return an end iterator of the parsed range. Throw an exception of type `bsl::format_error` in the event of failure.
