Struct EnterStringPage 

pub struct EnterStringPage<'a, T> {
    pub basic: BasicPage,
    pub buffer: String,
    /* private fields */
}

Page that allows to enter an ascii string composed of fixed set of characters.

Interaction is as follows:

• entering the page -> previous collected characters are shown

• entering the page first time -> factory default collected characters are shown

• next - selects the next character from the set of allowed characters

• previous - selects the previous character from the set of allowed characthers

• action - appends the selected character to the so far collected characters

• back - removes (most right character from the collected characters)

• home - leaves the page with UP-navigation

If previous button does not exist, next starts at the beginning after reaching the end.

Back can be emulated with next and action if not available. Home can be emulated with next and action if not available.

Fields

basic: BasicPage

buffer: String

Implementations

impl<'a, T: Copy + FromStr + Display> EnterStringPage<'a, T>

where <T as FromStr>::Err: Debug,

pub fn new( basic: BasicPage, allowed_characters: &'static str, back: Option<&'static str>, up: Option<&'static str>, value: &'a CellSetting<T>, ) -> Self

pub fn action_string(&self) -> &'static str

Process the action input

Action is one of:

• Add the selected character to internal buffer
• Remove last from internal buffer
• Finish the page and return to upper page.
  • Side effect: Update the value it page cares for

impl<T> PageBaseInterface for EnterStringPage<'_, T>

fn update<'a>( &mut self, _title_of_subpages: Option<Box<dyn Iterator<Item = &'a str> + 'a>>, ) -> Result<PageNavigation, PageError>

Trigger a page-internal update and causes page-internal state modification

fn title(&self) -> &str

Every page has a title - default is empty &str
