## 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:test_name\n",
        "SF:/path/to/source.rs\n",
        "DA:1,2\n",
        "DA:2,1\n",
        "DA:3,5\n",
        "end_of_record\n"
    );

    let records = LCOVParser::new(content.as_bytes()).parse().unwrap();

    for record in records.into_iter() {
        match record {
            LCOVRecord::TestName(name) => println!("Test: {}", name),
            LCOVRecord::SourceFile(file_name) => println!("File: {}", file_name),
            LCOVRecord::Data(line_number, execution_count, _) => println!("Line: {}, Executed: {}", line_number, execution_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("/path/to/report.lcov").unwrap();
let records = parser.parse().unwrap();

for record in records.iter() {
    match record {
        &LCOVRecord::SourceFile(ref name) => println!("start file: {}", name),
        &LCOVRecord::EndOfRecord => println!("end file"),
        _ => { continue; }
    }
}
```

### Parse of each record

If you want to parse one record at a time, you can use the next method.

```rust
use std::fs:: { File };
use lcov_parser:: { LCOVParser, FromFile };

let mut records = vec![];
let mut parser = LCOVParser::from_file("/path/to/file");

loop {
    let result = parser.next().unwrap();
    if result.is_none() {
        break;
    }
    let record = result.unwrap();
    records.push(record)
}

println!("{:?}", records);
println!("{:?}", records.len());
```
