Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

splatByte

Writes the same byte many times, allowing short writes.

Does maximum of one underlying VTable.drain.
