Struct InflateLimits 

#[non_exhaustive]
pub struct InflateLimits {
    pub max_entry_bytes: u64,
    pub max_ratio: u64,
    pub max_dex_total_bytes: u64,
}

Caps on what reading an APK may inflate, against zip bombs. The default only rejects what Deflate cannot produce; Limits::guarded is for sweeping untrusted APKs in bulk.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_entry_bytes: u64

Most bytes one entry may inflate to.

max_ratio: u64

Most an entry may expand over its compressed payload.

max_dex_total_bytes: u64

Most bytes all root DEX entries together may declare.

Implementations

impl Limits

pub const fn new() -> Limits

The default: only what Deflate cannot produce is rejected. A const fn, so that with the setters below limits can be constants.

pub const fn guarded() -> Limits

Real DEX files are at most a few hundred MiB and compress 2-5:1.

pub const fn max_entry_bytes(self, bytes: u64) -> Limits

These limits with at most bytes inflated per entry.

pub const fn max_ratio(self, ratio: u64) -> Limits

These limits with an entry expanding at most ratio times its compressed payload.

pub const fn max_dex_total_bytes(self, bytes: u64) -> Limits

These limits with at most bytes declared by all root DEX entries together.
