Sönke Ludwig 88308fcba4 Split up TaggedUnion and TaggedAlgebraic into separate modules. 2019-02-22 03:08:55 +01:00
Sönke Ludwig f7a03cdb02 Add enum support to TaggedUnion.

Sönke Ludwig 78ca6e0cb5 Reduce reliance on typeof(U.field) to prepare for supporting U==enum. 2019-02-22 03:08:54 +01:00
Sönke Ludwig 95c2919d2b Introduce TaggedUnion as the low-level basis for TaggedAlgebraic.
TaggedUnion has a number of convenience features compared to TaggedAlgebraic that are possible because of the missing dynamic dispatch functionality. If the latter is not required, TaggedUnion provides a much less complex and more robust way to store a fixed set of types/kinds.

String literal reduces memory allocation.
`-profile=gc` showed that `assert` allocated memory for every iteration.

John Colvin ffe296a96f do implicit casting without std.conv.to 2017-12-07 15:59:12 +00:00
Sönke Ludwig 513729bf59 Enable proper default initialization.
Since @disable this() still leaves an invalid .init open, TaggedAlgebraic.init has now been changed to always contain the .init value of the first specified sub type.

Note that this change is restricted to DMD 2.072 and up, because earlier versions of DMD do not allow postblits or destructors within unions and using a union appears to be the only way to implement this.

Sönke Ludwig 50e80dc0d9

Sönke Ludwig 96f18356f7 Output a proper error message when using hasType with an invalid type. Fixes #1. 2015-08-27 11:27:57 +02:00
Sönke Ludwig 84d6c8da80 Rename "type" to "kind".
Although there will be situations where the enum names equal the name of the types stored in a TaggedAlgebraic, "type" is often not the right term. It's also possible to define multiple fields of the same type, but with different names. "Kind" is used now as a more generic alternative.

Sönke Ludwig d02baa57ac Add opBinaryRight forwarding. 2015-08-17 15:53:47 +02:00
