Struct gif::MemoryLimit

source · [−]

pub struct MemoryLimit(pub u32);

Expand description

Memory limit in bytes. MemoryLimit(0) means that there is no memory limit set.

Tuple Fields

0: u32

Implementations

impl MemoryLimit

pub const NONE: MemoryLimit = MemoryLimit(0)

Enforce no memory limit.

If you intend to process images from unknown origins this is a potentially dangerous constant to use, as your program could be vulnerable to decompression bombs. That is, malicious images crafted specifically to require an enormous amount of memory to process while having a disproportionately small file size.

The risks for modern machines are a bit smaller as the dimensions of each frame can not exceed u32::MAX (~4Gb) but this is still a significant amount of memory.
