Struct VipsTarget 

pub struct VipsTarget { /* private fields */ }

A unified interface for writing data to various output destinations

Implementations

impl VipsTarget

pub fn new_to_writer<W: Writer>(output: W) -> Result<VipsTarget>

Create a target from a writer.

pub fn new_to_descriptor(descriptor: i32) -> Result<VipsTarget>

Create a target attached to a file descriptor. descriptor is kept open until the target is finalized.

pub fn new_to_file<P: AsRef<Path>>(filename: P) -> Result<VipsTarget>

Create a target attached to a file.

pub fn new_to_memory() -> Result<VipsTarget>

Create a target which will write to a memory area. Read from blob to get memory.

pub fn putc(&mut self, ch: char) -> Result<()>

Write a single character ch to target.

pub fn write(&mut self, buffer: &[u8]) -> Result<()>

Write buffer to the output.

pub fn writes(&mut self, text: &str) -> Result<()>

Write a string to target.

pub fn write_amp(&mut self, text: &str) -> Result<()>

Write str to target, but escape stuff that xml hates in text.

pub fn end(self)

Call this at the end of write to make the target do any cleaning up.

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

pub fn filename(&self) -> Option<String>

pub fn nick(&self) -> Option<String>

Trait Implementations

impl Clone for VipsTarget

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 VipsTarget

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

Formats the value using the given formatter.

impl Drop for VipsTarget

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
