Program

Struct Program 

Source
pub struct Program {
    pub ops: Vec<Op>,
}
Expand description

A bounded, ordered list of reconstruction instructions.

Fields§

§ops: Vec<Op>

Instructions, evaluated in order.

Implementations§

Source§

impl Program

Source

pub fn new(ops: Vec<Op>) -> Self

Wrap an instruction list.

Source

pub fn encode(&self) -> Result<Vec<u8>>

Encode the program to graph-record payload bytes.

Source

pub fn decode(data: &[u8], limits: Limits) -> Result<Program>

Decode a graph-record payload.

Source

pub fn analyze( &self, object_lens: &[u64], channel_lens: &[u64], limits: Limits, ) -> Result<(u64, CoverageMap)>

Walk the program, validating instruction semantics and returning both the predicted output length and the coverage certificate, using only object and channel lengths (no byte materialization, no large allocation).

Source

pub fn analyze_ops( &self, object_lens: &[u64], channel_lens: &[u64], limits: Limits, ) -> Result<Vec<u64>>

Walk the program and return the exact output length contributed by each instruction, in program order.

This is the op-indexed view of Program::analyze: per_op[i] is the number of bytes instruction i produces (0 for bookkeeping ops such as MARK_OFFSET), so per_op.iter().sum() == analyze(...).0. It applies the same validation and overflow checks as analyze; no rejection is relaxed. The optional observation index is checked against this view.

Source

pub fn analyze_inputs( &self, objects: &[Vec<u8>], channels: &[Vec<u8>], limits: Limits, ) -> Result<(u64, CoverageMap)>

Analyze using concrete object and channel tables.

Source

pub fn analyze_objects( &self, objects: &[Vec<u8>], limits: Limits, ) -> Result<(u64, CoverageMap)>

Convenience wrapper over Program::analyze for a program with no entropy channels.

Source

pub fn eval( &self, objects: &[Vec<u8>], channels: &[Vec<u8>], limits: Limits, ) -> Result<Vec<u8>>

Materialize the program’s output, enforcing all bounds.
