Struct FileFilter 

pub struct FileFilter { /* private fields */ }

Declarative acceptance rules for dropped files.

Implementations

impl FileFilter

pub fn new() -> Self

pub fn extensions<I, S>(self, exts: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Allow only these extensions (case-insensitive, no leading dot).

pub fn content_types<I, S>(self, types: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Allow only these MIME types. A trailing /* wildcard is supported ("image/*").

pub fn max_size(self, bytes: u64) -> Self

Reject files larger than this many bytes.

pub fn max_files(self, n: usize) -> Self

Accept at most this many files per drop.

pub fn check(&self, file: &FileData) -> Result<(), FileRejection>

Check a single file against the rules (ignores max_files).

pub fn partition( &self, files: Vec<FileData>, ) -> (Vec<FileData>, Vec<(FileData, FileRejection)>)

Split a batch into (accepted, rejected) applying every rule.

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

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.
