uri

struct GNUNET_FS_Uri* GNUNET_FS_TreeEncoder::uri

Set to the URI (upon successful completion)

Definition at line 75 of file fs_tree.c.

Referenced by GNUNET_FS_tree_encoder_finish(), GNUNET_FS_tree_encoder_get_uri(), and GNUNET_FS_tree_encoder_next().

size

uint64_t GNUNET_FS_TreeEncoder::size

Overall file size.

publish_offset

uint64_t GNUNET_FS_TreeEncoder::publish_offset

How far are we?

Definition at line 85 of file fs_tree.c.

How deep are we? Depth 0 is for the DBLOCKs.

Definition at line 90 of file fs_tree.c.

Referenced by GNUNET_FS_tree_encoder_next().

chk_tree_depth

unsigned int GNUNET_FS_TreeEncoder::chk_tree_depth

How deep is the tree? Always > 0.

chk_tree

struct ContentHashKey* GNUNET_FS_TreeEncoder::chk_tree

In-memory cache of the current CHK tree.

This struct will contain the CHK values from the root to the currently processed node in the tree as identified by "current_depth" and "publish_offset". The "chktree" will be initially NULL, then allocated to a sufficient number of entries for the size of the file and finally freed once the upload is complete.
