pub fn record_type(&self) -> RecordType

where RecordType: TryFromBytes,

Panics

Panics if the field’s bit pattern is not a valid value of the custom representation. Use Self::try_record_type to recover from invalid bit patterns.

pub fn try_record_type(&self) -> Result<RecordType, InvalidBits<u8>>

where RecordType: TryFromBytes,

Fallible variant of Self::record_type.
