Crate rust_code_analysis 

rust-code-analysis is a library to analyze and extract information from source codes written in many different programming languages.

You can find the source code of this software on GitHub, while issues and feature requests can be posted on the respective GitHub Issue Tracker.

Supported Metrics

• CC: it calculates the code complexity examining the control flow of a program.
• SLOC: it counts the number of lines in a source file.
• PLOC: it counts the number of physical lines (instructions) contained in a source file.
• LLOC: it counts the number of logical lines (statements) contained in a source file.
• CLOC: it counts the number of comments in a source file.
• BLANK: it counts the number of blank lines in a source file.
• HALSTEAD: it is a suite that provides a series of information, such as the effort required to maintain the analyzed code, the size in bits to store the program, the difficulty to understand the code, an estimate of the number of bugs present in the codebase, and an estimate of the time needed to implement the software.
• MI: it is a suite that allows to evaluate the maintainability of a software.
• NOM: it counts the number of functions and closures in a file/trait/class.
• NEXITS: it counts the number of possible exit points from a method/function.
• NARGS: it counts the number of arguments of a function/method.

Traits

Callback

A trait for callback functions.

Functions

action

Runs a function, which implements the Callback trait, on a code written in one of the supported languages.

count

Counts the types of nodes specified in the input slice and the number of nodes in a code.

dump_node

Dumps the AST of a code.

dump_ops

Dumps all operands and operators of a code.

dump_root

Dumps the metrics of a code.

find

Finds the types of nodes specified in the input slice.

fix_includes

Constructs a dependency graph of the include directives in a C/C++ file.

function

Detects the span of each function in a code.

get_from_emacs_mode
