Decoding limits

Fields

decoding_buffer_size: usize

The maximum size of any DecodingResult in bytes, the default is 256MiB. If the entire image is decoded at once, then this will be the maximum size of the image. If it is decoded one strip at a time, this will be the maximum size of a strip.

ifd_value_size: usize

The maximum size of any ifd value in bytes, the default is 1MiB.

intermediate_buffer_size: usize

Maximum size for intermediate buffer which may be used to limit the amount of data read per segment even if the entire image is decoded at once.

_non_exhaustive: ()

The purpose of this is to prevent all the fields of the struct from being public, as this would make adding new fields a major version bump.

Implementations

impl Limits

pub fn unlimited() -> Limits

A configuration that does not impose any limits.

This is a good start if the caller only wants to impose selective limits, contrary to the default limits which allows selectively disabling limits.

Note that this configuration is likely to crash on excessively large images since, naturally, the machine running the program does not have infinite memory.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Default for Limits

fn default() -> Limits

Returns the “default value” for a type.
