[−][src]Enum lcov::report::ParseError

pub enum ParseError {
    Read(Error),
    UnexpectedRecord(RecordKind),
    UnexpectedEof,
}

All possible errors that can occur when parsing LCOV records.

Variants

Read(Error)

An error indicating that reading record operation failed.

This error occurs when the underlying reader returns an error.

Examples

use lcov::{Reader, Report};
use lcov::report::ParseError;
assert_matches!(Report::from_reader(Reader::new("FOO:1,2,3".as_bytes())), Err(ParseError::Read(_)));
UnexpectedRecord(RecordKind)

An error indicating that unexpected kind of record is read.

This error occurs when the LCOV tracefile (or underlying reader) contains invalid record sequence.

Examples

use lcov::{Reader, Report, RecordKind};
use lcov::report::ParseError;
let input = "\
TN:test_name
SF:/usr/include/stdio.h
TN:next_test
";
assert_matches!(Report::from_reader(Reader::new(input.as_bytes())),
                Err(ParseError::UnexpectedRecord(RecordKind::TestName)));
UnexpectedEof

An error indicating that unexpected "end of file".

This error occurs when the LCOV tracefile (or underlying reader) contains invalid record sequence.

Examples

use lcov::{Reader, Report};
use lcov::report::ParseError;
let input = "\
TN:test_name
SF:/usr/include/stdio.h
";
assert_matches!(Report::from_reader(Reader::new(input.as_bytes())),
                Err(ParseError::UnexpectedEof));
