Expand description

The possible errors from a record read attempt

Variants§

§

CorruptRecord

This record is corrupt (failed a checksum), but we might be able to recover. A subsequent call to read_next() might yield the next record.

§

CorruptFile

The entire file is corrupted. This is a terminal error.

§

IoError

Fields

§source: Error

The underlying io::Error

There was an underlying io error. Depending on the source of the error, this may be a a transient or permanent failure.

§

BufferTooShort

Fields

§needed: u64

The length of the record that was too long to read.

The supplied buffer was too short to contain the next record.
