Zig's New Writer

10 months ago

Zig's Io namespace is being reworked, including the Writer and Reader interfaces.
The new Writer interface is std.Io.Writer, requiring a drain function for custom implementations.
Buffering is built into std.Io.Writer, with options to use or bypass it.
Custom writers can implement a simplified drain method, ignoring the splat parameter.
File.Writer is a struct that includes the std.Io.Writer interface, following a convention.
The Writer interface consolidates various writer-related methods, replacing older functions like std.fmt.formatIntBuf.
Legacy writers need an adaptToNewApi method to upgrade to the new interface.
The change integrates buffering directly into the Writer, differing from the compositional approach used in other languages.
