Expand description

A type of record data that can be composed.

Required Methods§

source

fn rdlen(&self, compress: bool) -> Option<u16>

Returns the length of the record data if available.

The method should return None, if the length is not known or is not the same for all targets.

If compress is true, name compression is available in the target. If name compression would be used in compose_rdata, the method should None if compress is true since it can’t know the final size.

source

fn compose_rdata<Target: Composer + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>

Appends the wire format of the record data into target.

source

fn compose_canonical_rdata<Target: Composer + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>

Appends the canonical wire format of the record data into target.

Provided Methods§

source

fn compose_len_rdata<Target: Composer + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>

Appends the record data prefixed with its length.

source

fn compose_canonical_len_rdata<Target: Composer + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>

Appends the record data prefixed with its length.

Object Safety§

This trait is not object safe.
