6.2.6.4. RustCloneDetection

Find clones in Rust files

Detects cloned sections in Rust files using structural comparison. Computes clones of type-1 (exact), type-2 (parameterized), and type-3 (near-miss) clones. All .rs files within the analyzed Rust project are processed, filtering options can be applied.

advanced

Advanced options for gxl or statistics output.

 

advanced.gxl_file : bauhaus.analysis.config.LayerRelativePath | None = None

Output found clones as GXL file.

 

advanced.pre_min_lines : int = 2

Minimum length in lines during hashing phase.

 

advanced.pre_min_weight : int = 2

Minimum weight in nodes during hashing phase.

 

advanced.stats_file : bauhaus.analysis.config.LayerRelativePath | None = None

Output statistics of found clones as CSV file.

 

max_density

max_density : int = 2147483647

Maximum density (weight/lines) of clone pairs to report in percent.

 

min_density

min_density : int = 0

Minimum density (weight/lines) of clone pairs to report in percent.

 

min_lines

min_lines : int = 30

Minimum length in lines of clone pairs to report.

 

min_weight

min_weight : int = 50

Minimum weight in nodes of clone pairs to report.

 

no_sequences

no_sequences : bool = False

Do not report cloned sequences.

 

pre_excludes

pre_excludes : set[bauhaus.analysis.config.GlobPattern] = set()

Set of globbing patterns of directories/filenames to exclude in early hashing phase. No clone pair with either left or right side matching those patterns is ever reported (e.g. */MemMap.h).

 

report_trait_impl_clones

report_trait_impl_clones : bool = False

If false, do not report clones between different impls of the same trait.

 

type3_similarity

type3_similarity : int = 80

Minimum similarity of type-3 clones to report in percent.
