Struct ParseLimits 

#[non_exhaustive]
pub struct ParseLimits {
    pub max_depth: u32,
    pub max_items: u32,
    pub max_expanded_bytes: u64,
}

Ceilings a handler applies while parsing.

Separate from crate::io::Limits, which bounds how much is read. These bound what a parser will do with what it read — the difference between refusing a 4 GB file and refusing a 4 KB file that describes four billion objects.

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_depth: u32

Maximum nesting depth.

Stack overflow aborts the process; it is not a catchable panic, so it cannot be handled after the fact and must be prevented by construction (docs/ARCHITECTURE.md §5.1).

max_items: u32

Maximum number of structural items — objects, segments, chunks — in one file.

max_expanded_bytes: u64

Maximum bytes a single compressed structure may expand to.

Reserved: no handler in this release uses it. Neither PNG nor WebP decompresses anything — PNG’s compressed text chunks are removed without being inflated (ADR-0022) — and the PDF handler declines to inflate a filtered metadata stream for the same reason. It is kept rather than removed because Phase 2’s ZIP-container formats cannot be attempted without it, and because a limit that exists is easier to review than one invented under deadline. It is documented as reserved rather than left looking enforced.
