Struct Stream 

pub struct Stream<'a>(/* private fields */);

A stream of arbitrary data.

Implementations

impl<'a> Stream<'a>

pub fn raw_data(&self) -> Cow<'a, [u8]>

Return the raw, decrypted data of the stream.

Stream filters will not be applied.

pub fn dict(&self) -> &Dict<'a>

Return the raw, underlying dictionary of the stream.

pub fn obj_id(&self) -> Option<ObjectIdentifier>

Return the object identifier of the stream, if available.

Returns None if the stream is corrupt and lacks an object ID.

pub fn filters(&self) -> &[Filter]

Return the filters that are applied to the stream.

pub fn decoded(&self) -> Result<Vec<u8>, DecodeFailure>

Return the decoded data of the stream.

Note that the result of this method will not be cached, so calling it multiple times is expensive.

pub fn decoded_shared(&self) -> Result<Arc<Vec<u8>>, DecodeFailure>

Like decoded, but decoded at most once per document load and shared: the cache is keyed by object number and generation.

For data many pages read again unchanged, such as embedded font programs. Not for images, whose decode depends on parameters. A stream without an object id is decoded each time.

pub fn decoded_image( &self, image_params: &ImageDecodeParams, ) -> Result<FilterResult, DecodeFailure>

Return the decoded data of the stream, and return image metadata if available.

Trait Implementations

impl<'a> Clone for Stream<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stream<'_>

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

Formats the value using the given formatter.

impl PartialEq for Stream<'_>

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

Equality operator ==.

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

Inequality operator !=.

impl<'a> TryFrom<Object<'a>> for Stream<'a>

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: Object<'a>) -> Result<Self, Self::Error>

Performs the conversion.
