Struct Blob

pub struct Blob { /* private fields */ }

A Blob.

Blobs can be created directly from &str, &[u8], and js_sys::ArrayBuffers using the Blob::new or Blob::new_with_options functions.

Implementations

impl Blob

pub fn new<T>(content: T) -> Blob

where T: BlobContents,

Create a new Blob from a &str, &[u8] or js_sys::ArrayBuffer.

pub fn new_with_options<T>(content: T, mime_type: Option<&str>) -> Blob

where T: BlobContents,

Like new, but allows specifying the MIME type (also known as content type or media type) of the Blob.

pub fn slice(&self, start: u64, end: u64) -> Self

pub fn size(&self) -> u64

The number of bytes in the Blob/File.

pub fn raw_mime_type(&self) -> String

The raw MIME type (also known as content type or media type) of the File or Blob.

Trait Implementations

impl AsRef<Blob> for Blob

fn as_ref(&self) -> &Blob

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<JsValue> for Blob

fn as_ref(&self) -> &JsValue

Converts this type into a shared reference of the (usually inferred) input type.

impl BlobContents for Blob

unsafe fn into_jsvalue(self) -> JsValue

Safety

impl Clone for Blob

fn clone(&self) -> Blob

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blob

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

Formats the value using the given formatter.

impl From<Blob> for Blob

fn from(blob: Blob) -> Self

Converts to this type from the input type.

impl From<Blob> for Blob

fn from(blob: Blob) -> Self

Converts to this type from the input type.

impl From<Blob> for JsValue

fn from(blob: Blob) -> Self

Converts to this type from the input type.

impl From<Blob> for ObjectUrl

fn from(blob: Blob) -> Self

Converts to this type from the input type.

impl From<File> for Blob

fn from(file: File) -> Self

Converts to this type from the input type.

impl From<File> for Blob

fn from(file: File) -> Self

Converts to this type from the input type.

impl PartialEq for Blob

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