Macro evegfx::format

format!() { /* proc-macro */ }

Constructs a Message value for use with EVE coprocessor commands that support string formatting.

This macro understands the format syntax just enough to automatically infer the types of any given arguments and thus produce a valid pairing of format string and arguments. However, it achieves that by parsing the format string at compile tLowLevelthe format string must always be a quoted string constant.

The coprocessor's formatter serves a similar purpose as Rust's own format functionality, but since the actual formatting operation happens inside the EVE coprocessor we can avoid including the potentially-large formatting code in memory-constrained systems. The EVE formatter can also interpolate strings already stored in the EVE RAM, via the %s verb, which Rust's own formatter doesn't have direct access to. Prepare a format string and associated arguments for use with an EVE coprocessor widget which supports the OPT_FORMAT option.
