Struct RawFormatter

pub struct RawFormatter { /* private fields */ }

Allows formatting of fmt::Arguments into a raw buffer.

It does not fail if callers write past the end of the buffer so that they can calculate the size required to fit everything.

Invariants

The memory region between pos (inclusive) and end (exclusive) is valid for writes if pos is less than end.
