pub async fn text(&self) -> String

impl<'js> Blob<'js>

pub fn from_bytes( ctx: &Ctx<'js>, data: Vec<u8>, content_type: Option<String>, ) -> Result<Self>

pub fn from_parts( ctx: Ctx<'js>, parts: Opt<Value<'js>>, options: Opt<Value<'js>>, ) -> Result<Self>

pub fn get_bytes(&self) -> Vec<u8>

pub fn array_buffer_ref(&self) -> ArrayBuffer<'js>

Zero-copy access to the underlying ArrayBuffer. Cloning the handle is cheap (it’s a JS-refcount bump); no bytes are copied. Useful for consumers that want to pass the Blob body on to hyper via ObjectBytes::DataView without the get_bytes() allocation.

pub fn as_bytes(&self) -> &[u8]

Borrow the underlying bytes directly. Returns &[] if the ArrayBuffer has been detached (shouldn’t happen in normal blob flow). The borrow carries 0.13’s obligation to the caller: no JS may run while the slice is alive.
