// conversion-gen is a tool for auto-generating Conversion functions.
|
|
//
|
|
// Given a list of input directories, it will scan for "peer" packages and
|
|
// generate functions that efficiently convert between same-name types in each
|
|
// package. For any pair of types that has a
|
|
// `Convert_<pkg1>_<type>_To_<pkg2>_<Type()`
|
|
// function (and its reciprocal), it will simply call that. use standard value
|
|
// assignment whenever possible. The resulting file will be stored in the same
|
|
// directory as the processed source package.
|
|
//
|
|
// Generation is governed by comment tags in the source. Any package may
|
|
// request Conversion generation by including a comment in the file-comments of
|
|
// one file, of the form:
|
|
// // +k8s:conversion-gen=<import-path-of-peer-package>
|
|
//
|
|
// When generating for a package, individual types or fields of structs may opt
|
|
// out of Conversion generation by specifying a comment on the of the form:
|
|
// // +k8s:conversion-gen=false
