lcov-parser

LCOV report parser for Rust.

Basic usage

Create a LCOVParser object, and then parse the data.

```rust extern crate lcov_parser;

use lcov_parser:: { LCOVParser, LCOVRecord };

fn main() { let content = concat!( "TN:testname\n", "SF:/path/to/source.rs\n", "DA:1,2\n", "DA:2,1\n", "DA:3,5\n", "endofrecord\n" ); let mut parser = LCOVParser::new(content.asbytes());

loop {
    match parser.next().expect("parse the report") {
        None => { break; },
        Some(record) => match record {
            LCOVRecord::TestName(name) => println!("Test: {}", name.unwrap()),
            LCOVRecord::SourceFile(file_name) => println!("File: {}", file_name),
            LCOVRecord::Data(data) => println!("Line: {}, Executed: {}", data.line, data.count),
            LCOVRecord::EndOfRecord => println!("Finish"),
            _ => { continue; }
        }
    }
}

} ```

Parsing the file

It can also be used to parse the report file.

```rust let mut parser = LCOVParser::from_file("../../../fixture/report.lcov").unwrap();

loop { match parser.next().expect("parse the report") { None => { break; }, Some(record) => match record { LCOVRecord::SourceFile(filename) => println!("File: {}", filename), LCOVRecord::EndOfRecord => println!("Finish"), _ => { continue; } } } } ```

Parsing all

You can parse all using the parse method.

```rust let records = { let mut parser = LCOVParser::from_file("../../../fixture/report.lcov").unwrap(); parser.parse().expect("parse the report") };

for record in records.iter() { match record { &LCOVRecord::SourceFile(ref filename) => println!("File: {}", filename), &LCOVRecord::EndOfRecord => println!("Finish"), _ => { continue; } } } ```

Merge reports

You use merge_files to merge reports.
You can save the merged report by specifying the file name.

```rust extern crate lcov_parser;

use lcovparser:: { mergefiles };

fn main() { let tracefiles = [ "../../../tests/fixtures/fixture1.info", "../../../tests/fixtures/fixture2.info" ]; let _ = match mergefiles(&tracefiles) { Ok(report) => report.saveas("/tmp/merged_report.info"), Err(err) => panic!(err) }; } ```
