Struct Session 

pub struct Session { /* private fields */ }

Caller-owned lifetime of one PDF source session and its original work ceiling. The existing shared parser owns the same execution boundary used by genuinely carried DER CMS/PKIX values; PDF bytes are not parsed as ASN.1. Source and current-operation work compose through the existing shared execution kernel, without another account, reset or allocator wrapper.

Implementations

impl Session

pub fn new(limits: Limits, memory: Memory) -> Self

Constructs trusted session state without allocation or source traversal.

pub fn limits(&self) -> Limits

Immutable caller-selected mechanism ceilings.

pub fn execution(&self) -> Execution<'_>

Original source work and allocation account, without a new cursor or account-owner clone. Every data-dependent operation must admit work.

pub fn query<'a, W: Work>(&'a self, operation: &'a W) -> Execution<'a>

Attaches the current operation while retaining the original source ceiling. Cross-source queries preserve the original root operation; sharing an account does not exempt either ceiling.

pub fn object(&self, location: Location) -> Result<()>

Counts an object before parsing or allocating its representation.

pub fn revision(&self, location: Location) -> Result<()>

Counts a revision before traversing its cross-reference section.

pub fn decode(&self, amount: u64, location: Location) -> Result<()>

Counts potential decoded output before running a decoder. This output allowance is cumulative; discarding storage never refunds completed work.
