Prefer importing this trait through the prelude:

Provided Methods§

source

fn iter(&self) -> impl Iterator<Item = HrResult<IShellItem>> + '_

Returns an iterator over the IShellItem elements which calls IEnumShellItems::Next internally.

§Examples

Enumerating the items in a folder by iterating over the IShellItem objects:

use winsafe::{self as w, prelude::*, co};

let folder = w::SHCreateItemFromParsingName::<w::IShellItem>(
    "C:\\Temp",
    None::<&w::IBindCtx>,
)?;

let items = folder.BindToHandler::<w::IEnumShellItems>(
    None::<&w::IBindCtx>,
    &co::BHID::EnumItems,
)?;

for item in items.iter() {
    let item = item?;
    println!("{}", item.GetDisplayName(co::SIGDN::FILESYSPATH)?);
}
