Struct CodeImage

pub struct CodeImage {
    pub programs: BTreeMap<String, Vec<Instr>>,
    pub global_type: GlobalType,
    pub local_types: BTreeMap<String, LocalTypeR>,
}

Expand description

A verified code image: program + global type + local types.

In the Lean spec, this carries well-formedness and projection correctness proofs. In Rust, the proofs are replaced by runtime validation that was performed before constructing the image.

Fields§

§programs: BTreeMap<String, Vec<Instr>>

Bytecode programs per role.

§global_type: GlobalType

The global type this image was derived from.

§local_types: BTreeMap<String, LocalTypeR>

Projected local types per role.

Implementations§

impl CodeImage

pub fn from_local_types( local_types: &BTreeMap<String, LocalTypeR>, global_type: &GlobalType, ) -> Self

Create a code image from projected local types by compiling each to bytecode.

pub fn roles(&self) -> Vec<String>

Role names in this image.

pub fn validate_runtime_shape(&self) -> Result<(), String>

Validate trusted-image runtime shape constraints.

§Errors

Returns an error string when the image shape violates ProtocolMachine runtime expectations (role coverage, type coverage, or global well-formedness).
