Struct DecodeLimits 

pub struct DecodeLimits {
    pub max_encoded_bytes: usize,
    pub max_pixels: u64,
    pub max_frames: u32,
}

DecodeLimits bounds what a decode may consume, so hostile bytes cannot exhaust memory.

Fields

max_encoded_bytes: usize

max_encoded_bytes bounds the input file.

max_pixels: u64

max_pixels bounds one frame at its source size, before any downscale.

max_frames: u32

max_frames bounds the frame count an animation may declare.

Implementations

impl DecodeLimits

pub fn check_source_size(self, size: [u32; 2]) -> Result<(), DecodeError>

check_source_size rejects an empty or too-large frame before any pixels are allocated.

pub fn check_frame_count(self, count: u32) -> Result<(), DecodeError>

check_frame_count rejects an image with no frames or more than the limit.
