Struct InflateLimits 

pub struct InflateLimits {
    pub grace_size: u64,
    pub max_expansion: u64,
    pub max_size: u64,
}

How far compressed data may expand before it is taken for a decompression bomb.

Fields

grace_size: u64

The output up to which the ratio is not checked: a small output cannot exhaust memory however well it compresses (a part of zeros, a blank picture).

max_expansion: u64

Past Self::grace_size, the most the output may be as a multiple of the compressed size.

max_size: u64

The most the output may be at all.

Implementations

impl InflateLimits

pub const POI: Self

Apache POI’s ZipSecureFile defaults: GRACE_ENTRY_SIZE 100 KiB, MIN_INFLATE_RATIO 0.01 (at most 100 times), MAX_ENTRY_SIZE 4 GiB (the 32-bit ZIP limit).

pub fn allows(&self, compressed: u64, inflated: u64) -> bool

Whether inflated bytes of output from compressed bytes stay within these limits.

pub fn check(&self, compressed: u64, inflated: u64) -> Result<()>

Self::allows as a result: the error InflateGuard fails with when it does not.
