[−][src]Enum lcov::report::MergeError

pub enum MergeError {
    UnmatchedFunctionLine,
    UnmatchedChecksum,
}

All possible errors that can occur when merging LCOV records.

Variants

UnmatchedFunctionLine

An error indicating that start line of functions are not same.

This error occurs when merging not compatible LCOV tracefiles.

Examples

use lcov::{Reader, Report};
use lcov::report::MergeError;
let input1 = "\
TN:test_name
SF:foo.c
FN:3,foo
end_of_record
";
let input2 = "\
TN:test_name
SF:foo.c
FN:4,foo
end_of_record
";
let mut report1 = Report::from_reader(Reader::new(input1.as_bytes()))?;
let report2 = Report::from_reader(Reader::new(input2.as_bytes()))?;
assert_matches!(report1.merge(report2),
                Err(MergeError::UnmatchedFunctionLine));
UnmatchedChecksum

An error indicating that checksum of lines are not same.

This error occurs when merging not compatible LCOV tracefiles.

Examples

use lcov::{Reader, Report};
use lcov::report::MergeError;
let input1 = "\
TN:test_name
SF:foo.c
DA:4,1,valid_checksum
end_of_record
";
let input2 = "\
TN:test_name
SF:foo.c
DA:4,4,invalid_checksum
end_of_record
";
let mut report1 = Report::from_reader(Reader::new(input1.as_bytes()))?;
let report2 = Report::from_reader(Reader::new(input2.as_bytes()))?;
assert_matches!(report1.merge(report2),
                Err(MergeError::UnmatchedChecksum));
