pub fn focus_prev(&mut self)

Retreat the focused field to the previous one (skipping remote fields when tunnel_type is Dynamic) and sync the cursor to the end of the new focused value.

pub fn validate(&self) -> Result<(), String>

Validate the form. Returns error message if invalid.

pub fn to_directive(&self) -> (&'static str, String)

pub fn insert_char(&mut self, c: char)

pub fn delete_char_before_cursor(&mut self)
