Struct TreeNode 

Source
pub struct TreeNode {
    pub index: MediaRef,
    pub trigram: Option<MediaRef>,
    pub bloom: String,
    pub files: u64,
    pub bytes: u64,
}
Expand description

A directory node of a tree mint (design doc: tree-scale). When a token names a directory minted --tree, it carries one of these instead of a flat list of per-file child tokens: the directory’s index (files pinned by hash, subdirs addressed by their own subtree token), the trigram index over its files, and a Bloom summary of every trigram beneath it, inlined so a search can prune the subtree from the manifest alone. Files pin their bytes eagerly (so a deleted file still reads — C-1) and are addressed by name within their node (read --file); a file is not itself a token, so a folder of thousands mints as a handful of nodes, not thousands of tokens.

The bloom is the lowercase-hex wire form of a fixed-size filter (parsed into the typed structure by the consumer, waggle-tree::Bloom); keeping it a string here preserves this crate’s dependency-free leaf position. Immutable core — signed; absent for non-tree mints, so their manifests keep their exact bytes.

Fields§

§index: MediaRef

Content-addressed directory index for THIS node (its direct entries).

§trigram: Option<MediaRef>

Content-addressed trigram index over this node’s own files; absent when the node has no indexable text of its own (e.g. only subdirectories).

§bloom: String

Hex Bloom summary of every trigram in this subtree — inlined for prune.

§files: u64

Files anywhere beneath this node (recursive).

§bytes: u64

Bytes anywhere beneath this node (recursive).
