Make-bip32-key-tree

Basic constructor macro for bip32-key-tree structures.

Syntax

(make-bip32-key-tree [:root-key <root-key>] 
                     [:root-depth <root-depth>] 
                     [:root-index <root-index>] 
                     [:root-parent <root-parent>] 
                     [:index-tree <index-tree>]) 

This is the usual way to construct bip32-key-tree structures. It simply conses together a structure with the specified fields.

This macro generates a new bip32-key-tree structure from scratch. See also change-bip32-key-tree, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-bip32-key-tree

(defmacro make-bip32-key-tree (&rest args)
  (std::make-aggregate 'bip32-key-tree

                         (:root-depth)
                         (:root-index)
                         (:root-parent)
                         (:index-tree))
                       'make-bip32-key-tree
