This line of code causes me to print lots of annoying warnings when I used.

[AbelChe]

html5ever/html5ever/src/tree_builder/mod.rs

Line 1149 in 98d3c0c

warn!("foster parenting not implemented");

Is there any way to prevent it from displaying warnings, or will the next version provide a switch to manage whether html5erver prints logs?

You can control which modules print logs from your app.
