Struct domain::base::message_builder::TreeCompressor

source ·
pub struct TreeCompressor<Target> { /* private fields */ }
Expand description

A domain name compressor that uses a tree.

This type wraps around an octets builder and implements domain name compression for it. It stores the position of any domain name it has seen in a binary tree.

The position of a domain name is calculated relative to the beginning of the underlying octets builder. This means that this builder must represent the message only. This means that if you are using the StreamTarget, you need to place it inside this type, not the other way around.

Implementations§

source§

impl<Target> TreeCompressor<Target>

source

pub fn new(target: Target) -> Self
