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.

init_single_threaded

Statically initialize such that calls to Io.VTable.concurrent will fail with error.ConcurrencyUnavailable.

When initialized this way:

cancel requests have no effect.
deinit is safe, but unnecessary to call.
