Struct CpdClone 

pub struct CpdClone {
    pub format: String,
    pub fragment_a: Fragment,
    pub fragment_b: Fragment,
    pub token_count: u32,
    pub is_new: bool,
    pub kind: CloneKind,
    pub similarity: Option<f32>,
    pub similarity_method: Option<SimilarityMethod>,
    pub unmatched_lines: [u32; 2],
}

Fields

format: String

fragment_a: Fragment

fragment_b: Fragment

token_count: u32

is_new: bool

True when the clone is absent from the configured baseline (issue #944). Always false when no baseline is in use.

kind: CloneKind

exact when the raw tokens of both fragments are identical, renamed when they match only after normalization (issue #998). Always exact when no normalization option is on.

similarity: Option<f32>

For similar clones: matched tokens divided by the tokens of the longer merged span, in (0, 1). None for exact and renamed clones.

similarity_method: Option<SimilarityMethod>

Which mechanism produced a similar clone; the two scores are not on the same scale, so reporters show it next to the value.

unmatched_lines: [u32; 2]

Lines inside each fragment’s span that are not duplicated code, for fragment_a and fragment_b in that order. Two things land here: the lines a --max-gap-lines merge left unmatched between its halves, and, for an embedded block, the host language’s lines lying between two blocks of the same fragment (issue #1090). Statistics subtract them from the fragment’s span.

Implementations

impl CpdClone

pub fn matched_lines(&self) -> u64

Duplicated lines this clone adds to the statistics: the matched lines of its primary fragment.

pub fn fragment_lines(&self, index: usize) -> u64

Matched lines of one fragment — 0 is A, 1 is B. Per-file summaries need both, and they must not drift apart.

The span is inclusive, so a clone of lines 10 through 19 is ten lines, the same count the reporters print next to it. Whatever the span covers but does not duplicate — gap-merge lines, host-language lines between two embedded blocks — is already in unmatched_lines.

pub fn exact( format: impl Into<String>, fragment_a: Fragment, fragment_b: Fragment, token_count: u32, ) -> Self

An exact clone with no baseline, similarity or gap metadata.

pub fn similarity_rounded(&self) -> Option<f64>

similarity rounded to three decimals as an f64, the form reporters print (an f32 widened to JSON would print as 0.8510638475418091).
