Struct Fingerprint 

pub struct Fingerprint {
    pub digest: [u8; 32],
    pub node_count: u32,
}

One function-or-file’s structural fingerprint.

Fields

digest: [u8; 32]

256-bit SHA-256 of the pre-order (kind_name, child_count) byte sequence (identifiers, literals, and comments omitted).

node_count: u32

Number of AST nodes that contributed to the fingerprint (i.e. the nodes that survived the identifier/literal skip filter). Use this as the minimum-fragment-size knob to drop trivial getters/setters.

Implementations

impl Fingerprint

pub fn hex(&self) -> String

Render the digest as lowercase hex for CSV/JSON output.

pub fn from_sequence(sequence: &[(&str, u16)]) -> Self

Build a Fingerprint directly from a pre-computed (kind_name, arity) sequence. Used by the function extractor in clones::extractor so it can run the same walk over a subtree (the function body) instead of the full file.

Trait Implementations

impl Clone for Fingerprint

fn clone(&self) -> Fingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
