10. Compile errors Setu raises#

What the message says: the cause.

• anytype parameters are not supported: a pub fn with an anytype parameter is exported
• only plain required parameters can come before py.Rest: a default / ?T / struct / KwOnly before *args
• py.Kwargs must be the last parameter
• more than one py.KwOnly
• the required parameter b comes after a, which has a default: section 1, rule 4
• py.KwOnly after py.Rest is redundant: after *args everything is keyword-only already
• py.Rest / py.Kwargs are not supported here; take one setu.CallArgs parameter: __new__ / __init__ / __call__
• no default for x in the source: the argument struct's default is not in the file (structBody)
• the argument struct Opts must be declared in the same file
• can't show the default ... in Python; use a literal, null or a constant: a default the stub can not render
• no pub fn name( in source / no const Name = struct { in source: the @embedFile is not the declaration's file
• pub fn x needs the entry's .source = @embedFile(...): a function in a from entry without source
• .only and .exclude together / .only names x, which it does not declare
• x is in the module twice: a.x and b.x: one Python name from two declarations
• A.T and B.T are the same type: one setu.Class / setu.Exception type under two names
• its base pkg.Base is in no Module.from entry
• Module.methods must end with py.method_end (or set from, version or init): a table without its terminator
• unsupported parameter type / result type T: an int over 64 bits, a non-slice pointer, a plain struct result, ...
• checkErrno takes a signed int
• Sequence(OwnedBuffer): the items are released with the sequence: use Sequence(Buffer) and take
• take of an owned buffer: it is the function's already
• a py.Buffer hook parameter is never released; take *Object and convert it in the hook: a buffer / Path / Sequence hook parameter
• __poll__ generates __send__; give one / __send__ / __poll__ generate __iter__ and __next__
• pickle needs an instantiable type / T.f: a U can not be pickled: pickle = true with instantiable = false or a bad field
• cls must be *c.TypeObject: a class method's first parameter
• __hash__ must return an int / __len__ an unsigned int / __next__ ?R / __int__ an int / __float__ a float: result types
• __get__ takes instance: ?*Object, owner: ?*Object
• needs pub const module: setu.Module in the root file, for the module name: a setu.Class with no module in the root
• method m: parameter p stubs as Any; if it is a Zig-only helper rename it camelCase, else add a Type entry: 7
• not in the 3.15 stable ABI (abi3t), which Setu builds for: a c.* tombstone; use the replacement it names
