Struct MemoryStream 

pub struct MemoryStream { /* private fields */ }

In-memory stream supporting both read and write access.

Port of CFX_MemoryStream (cfx_memorystream.h/cpp). Implements both PdfSource (read) and PdfWrite (write).

Implementations

impl MemoryStream

pub fn new() -> Self

Create an empty MemoryStream.

pub fn from_bytes(data: Vec<u8>) -> Self

Create a MemoryStream from existing bytes.

pub fn into_bytes(self) -> Vec<u8>

Consume the stream and return the underlying bytes.

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

Return a slice of the stream’s bytes.

Trait Implementations

impl AsRef<[u8]> for MemoryStream

fn as_ref(&self) -> &[u8]

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

impl Default for MemoryStream

fn default() -> Self

Returns the “default value” for a type.

impl PdfSource for MemoryStream

fn len(&self) -> usize

Total size in bytes.

fn is_empty(&self) -> bool

Returns true if the source contains no bytes.

impl PdfWrite for MemoryStream

fn write_bytes(&mut self, data: &[u8]) -> Result<()>

Write raw bytes to the output.

fn position(&self) -> u64

Current byte offset in the output.

impl WriteStream for MemoryStream

fn write_block(&mut self, data: &[u8]) -> bool

Write data to the stream. Empty slice is a no-op; returns true.
