Struct FileFilter 

pub struct FileFilter { /* private fields */ }

One entry in the chooser’s file-type dropdown.

Globs and MIME types are both accepted because the portal backends differ in which they honour; supplying both is the portable choice.

Implementations

impl FileFilter

pub fn new(name: &str) -> FileFilter

A filter labelled name in the chooser’s type dropdown.

pub fn globs(&self) -> &[String]

Match files by shell glob, e.g. *.png. The globs this filter offers, so an app can assert that its chooser advertises everything it can open — a filter narrower than the reader behind it hides a user’s file with no way to discover the app would have taken it.

pub fn glob(self, g: &str) -> FileFilter

pub fn mimetype(self, m: &str) -> FileFilter

Match files by MIME type, e.g. application/pdf.

pub fn all_files() -> FileFilter

The “All files” escape hatch every picker should offer, so the user is never trapped by a file with an unusual MIME type.

pub fn mimetypes(&self) -> &[String]

The MIME types this filter offers.

pub fn name(&self) -> &str

Trait Implementations

impl Clone for FileFilter

fn clone(&self) -> FileFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileFilter

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

Formats the value using the given formatter.

impl Default for FileFilter

fn default() -> FileFilter

Returns the “default value” for a type.

impl PartialEq for FileFilter

fn eq(&self, other: &FileFilter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
