The types, values, and functions are defined as their Go 19 // equivalence and mapped to CUE types. 20 // 21 // Beware that some packages are defined in lesser-precision types than are 22 // typically used in CUE and thus may lead to loss of precision. 23 // 24 // All packages except those defined in the tool subdirectory are hermetic, 25 // that is depending only on a known set of inputs, and therefore can guarantee 26 // reproducible results. That is: 27 // 28 // - no reading of files contents 29 // - no querying of the file system of any kind 30 // - no communication on the network 31 // - no information about the type of environment 32 // - only reproducible random generators 33 // 34 // Hermetic configurations allow for fast and advanced analysis that otherwise 35 // would not be possible or practical. The cue "cmd" command can be used to mix 36 // in non-hermetic influences into configurations by using packages defined 37 // in the tool subdirectory. 38 package pkg 39 40 //go:generate go run gen.go 41
