lcov-parser
LCOV report parser for Rust.
Basic usage
Create a LCOVParser object, and then parse the data.
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 mut parser = LCOVParser::new(content.as_bytes());
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.
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(file_name) => println!("File: {}", file_name),
LCOVRecord::EndOfRecord => println!("Finish"),
_ => { continue; }
}
}
}
Parsing all
You can parse all using the parse method.
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 file_name) => println!("File: {}", file_name),
&LCOVRecord::EndOfRecord => println!("Finish"),
_ => { continue; }
}
}
