FnHelp

improv_tui::fnhelp

Struct FnHelp 

Source 
pub struct FnHelp {
    pub query: String,
    pub results: Vec<&'static FnDef>,
    pub selected: usize,
    pub top: usize,
    pub page: usize,
}
Expand description

The open help overlay.

Fields§

§query: String

The search line, filtered through [functions::search].

§results: Vec<&'static FnDef>

Functions matching query, best first.

§selected: usize

Index of the selected result.

§top: usize

First visible result row; the renderer scrolls it to the selection.

§page: usize

Rows the result list showed last render; PgUp/PgDn move by this.

Implementations§

Source§

impl FnHelp

Source

pub fn new() -> FnHelp

An overlay listing every function, the first one selected.

Source

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

Type a character into the search line.

Source

pub fn pop(&mut self)

Delete the last search character.

Source

fn refilter(&mut self)

Source

pub fn step(&mut self, delta: isize)

Move the selection by delta rows, clamped to the results.

Source

pub fn page_by(&mut self, dir: isize)

Move the selection a page up (-1) or down (1).

Source

pub fn current(&self) -> Option<&'static FnDef>

The selected function, if any result matched.

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
