Struct OpenFile 

pub struct OpenFile { /* private fields */ }

A native “open file” picker. .await (or .present().await) resolves to the chosen FileUrl, or None if the user cancels.

let file = open_file().filter("Text", &["txt", "md"]).await;
if let Some(f) = file { let body = f.read_to_string()?; }

Implementations

impl OpenFile

pub fn title<M>(self, t: impl IntoText<M>) -> Self

Override the picker’s title (localizable via tr()).

pub fn filter(self, name: impl Into<String>, extensions: &[&str]) -> Self

Add a named file-type filter, e.g. .filter("Text", &["txt", "md"]). No filter = all files.

pub async fn present(self) -> Option<FileUrl>

Trait Implementations

type Output = Option<FileUrl>

The output that the future will produce on completion.

type IntoFuture = Pin<Box<dyn Future<Output = Option<FileUrl>>>>

Which kind of future are we turning this into?
