tech.v3.datatype.struct
Structs are datatypes composed of primitive datatypes or other structs. Similar to records except they do not support string or object columns, only numeric values. They have memset-0 initialization, memcpy copy semantics. For correct equals, hashing, convert struct into a normal diff --git a/docs/tech.v3.datatype.wavelet.html b/docs/tech.v3.datatype.wavelet.html index 5968485c..6a171e71 100644 --- a/docs/tech.v3.datatype.wavelet.html +++ b/docs/tech.v3.datatype.wavelet.html @@ -4,7 +4,7 @@ function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); - gtag('config', 'G-95TVFC1FEB');
