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, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Fail for Error

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for Error

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

Formats the value using the given formatter.
