Enum lcov::reader::Error

pub enum Error {
    Io(Error),
    ParseRecord(u32, ParseRecordError),
}

All possible errors that can occur when reading LCOV tracefile.

Variants

Io(Error)

An error indicating that I/O operation failed.

This error occurs when the underlying reader returns an error.

ParseRecord(u32, ParseRecordError)

An error indicating that record parsing failed.

Examples

use lcov::Reader;
use lcov::reader::Error as ReadError;
use lcov::record::ParseRecordError;
let mut reader = Reader::new("FOO:1,2".as_bytes());
assert_matches!(reader.next(), Some(Err(ReadError::ParseRecord(1, ParseRecordError::UnknownRecord))));

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, req: &mut Demand<'a>)

🔬 This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ParseError

fn from(source: Error) -> Self

Converts to this type from the input type.
