Enum lcov::record::ParseRecordError

pub enum ParseRecordError {
    FieldNotFound(&'static str),
    TooManyFields,
    ParseIntError(&'static str, ParseIntError),
    UnknownRecord,
}

All possible errors that can occur when parsing LCOV record.

Variants

FieldNotFound(&'static str)

An error indicating that the field of the record is not found in the input.

Examples

use lcov::Record;
use lcov::record::ParseRecordError;
assert_eq!("FNDA:3".parse::<Record>(), Err(ParseRecordError::FieldNotFound("name")));

TooManyFields

An error indicating that the number of fields is larger than expected.

Examples

use lcov::Record;
use lcov::record::ParseRecordError;
assert_eq!("LF:1,2".parse::<Record>(), Err(ParseRecordError::TooManyFields));

ParseIntError(&'static str, ParseIntError)

An error indicating that parsing integer field failed.

Examples

use lcov::Record;
use lcov::record::ParseRecordError;
assert_matches!("LH:foo".parse::<Record>(), Err(ParseRecordError::ParseIntError("hit", _)));

UnknownRecord

An error indicating that the unknown record is found in the input.

Example

use lcov::Record;
use lcov::record::ParseRecordError;
assert_eq!("FOO:1,2".parse::<Record>(), Err(ParseRecordError::UnknownRecord));

Trait Implementations

impl Clone for ParseRecordError

fn clone(&self) -> ParseRecordError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseRecordError

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

Formats the value using the given formatter.

impl Display for ParseRecordError

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

Formats the value using the given formatter.

impl Error for ParseRecordError

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.
