[−][src]Enum lcov::report::MergeError
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));
