Struct term_basics_linux::InputList

pub struct InputList { /* private fields */ }

A struct that holds inputs available for the user to scroll through.

Implementations

impl InputList

pub fn new(maxlen: usize) -> Self

Make a new InputList with a certain maximum capacity.

Example

use term_basics_linux as tbl;
let mut his = tbl::InputList::new(10);
let x = tbl::input_field_scrollable(&mut his, true);

pub fn add(&mut self, string: &str)

Adds an element to the list. It will delete items if it’s length would grow past the max length. the oldest items will be removed.

Example

use term_basics_linux as tbl;
let mut his = tbl::InputList::new(2);
his.add(&"0".to_string());
his.add(&"1".to_string());
his.add(&"2".to_string());
// only "1" and "2" will remain, as 0 is removed.
let _ = tbl::input_field_scrollable(&mut his, true);

pub fn get_index(&self, index: i32) -> Option<&String>

Returns the an Option of String, the element at the given index. The index wraps and you can query for negative indices as well as indices above the maximum length.

Example

use term_basics_linux as tbl;
let mut his = tbl::InputList::new(3);
his.add(&"0".to_string());
his.add(&"1".to_string());
his.add(&"2".to_string());
println!("at -2: {:?}", his.get_index(-2)); // "1"
println!("at -1: {:?}", his.get_index(-1)); // "2"
println!("at  0: {:?}", his.get_index(0));  // "0"
println!("at  1: {:?}", his.get_index(1));  // "1"
println!("at  2: {:?}", his.get_index(2));  // "2"
println!("at  3: {:?}", his.get_index(3));  // "0"
println!("at  4: {:?}", his.get_index(4));  // "1"
