Struct UploadAccept

pub struct UploadAccept { /* private fields */ }

Normalized extension and MIME patterns accepted by an upload control.

Supported forms are .ext, an exact MIME type such as image/png, and a top-level wildcard such as image/*. An empty pattern set accepts all files.

Examples

use ailloli_ui_core::UploadAccept;

let accept = UploadAccept::new([".png", "image/*"]);
assert_eq!(accept.patterns(), [".png", "image/*"]);

Implementations

impl UploadAccept

pub fn new(patterns: impl IntoIterator<Item = impl Into<String>>) -> Self

Normalizes and stores the supplied patterns in input order.

Patterns are trimmed, converted to lowercase, and empty entries are discarded. Duplicates and unsupported forms are preserved but do not gain special matching behavior.

Examples

use ailloli_ui_core::UploadAccept;

let accept = UploadAccept::new([" .PNG ", ""]);
assert_eq!(accept.patterns(), [".png"]);

pub fn is_empty(&self) -> bool

Returns true when there are no effective restrictions.

Examples

use ailloli_ui_core::UploadAccept;

assert!(UploadAccept::default().is_empty());

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

Returns normalized patterns in their original relative order.

Examples

use ailloli_ui_core::UploadAccept;

assert_eq!(UploadAccept::new([".PNG"]).patterns(), [".png"]);

pub fn accepts(&self, file: &UploadFile) -> bool

Returns whether at least one pattern matches file.

Extension patterns use UploadFile::name; MIME patterns require a UploadFile::mime_hint. With no patterns this returns true.

Examples

use ailloli_ui_core::{UploadAccept, UploadFile};

let images = UploadAccept::new([".png", "image/*"]);
assert!(images.accepts(&UploadFile::named("avatar.PNG")));
assert!(!images.accepts(&UploadFile::named("notes.txt")));

Trait Implementations

impl Clone for UploadAccept

fn clone(&self) -> UploadAccept

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UploadAccept

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

Formats the value using the given formatter.

impl Default for UploadAccept

fn default() -> UploadAccept

Returns the “default value” for a type.

impl PartialEq for UploadAccept

fn eq(&self, other: &UploadAccept) -> 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.
