Trait RecordReader

pub trait RecordReader: Sized {
    const REC_TYPE: QType;
    const RLEN: u16;

    // Required methods
    fn read(
        pkt: &mut Cursor<&[u8]>,
        rlen: u16,
        qtype: QType,
    ) -> CDnsResult<Self>;
    fn wrap(self) -> DnsRdata;
}

Trait for decoding DNS record structures from bytes read over the wire.

Required Associated Constants

const REC_TYPE: QType

A QType a record type for current instance

const RLEN: u16

A data size

Required Methods

fn read(pkt: &mut Cursor<&[u8]>, rlen: u16, qtype: QType) -> CDnsResult<Self>

Read at most len bytes from the given Cursor. This cursor travels throughout the complete data — by this point, we have read the entire response into a buffer.

fn wrap(self) -> DnsRdata

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
