Struct Widget 

pub struct Widget {
    pub flags: i32,
    pub first: Option<Box<thingy>>,
    pub u: WidgetImpl,
}

Fields

flags: i32

flags (see below).

first: Option<Box<thingy>>

`first’ thingy that names this widget.

u: WidgetImpl

Tagged equivalent of the C anonymous union (zle.h:194-202).

Implementations

impl widget

pub fn internal(name: &str, func: fn(&[String]) -> i32, flags: i32) -> widget

Build a widget that points at a Rust function pointer with the supplied ZLE flags. Equivalent to the WIDGET_INT branch of zalloc(sizeof(*w)) + w->u.fn = ... in addzlefunction() at Src/Zle/zle_thingy.c:281.

pub fn builtin(name: &str) -> widget

Resolve a built-in widget name to its canonical fn pointer via zle_bindings::iwidget_lookup. Mirrors the dispatch C achieves at Src/Zle/zle_bindings.c:55-60 through the generated widgets[] static table; the Rust port uses a name → fn-pointer match keyed off the same iwidgets.list canonical names. Unknown widget names get a no-op fn pointer (matches what t_undefinedkey resolves to).

pub fn user_defined(name: &str, func_name: &str) -> widget

Build a widget that wraps a user-defined shell function. Equivalent to bin_zle_new() from Src/Zle/zle_thingy.c:584.

Trait Implementations

impl Clone for widget

fn clone(&self) -> widget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for widget

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
