Struct ExecutionContract 

pub struct ExecutionContract {
    pub format_version: u32,
    pub kind: EffectKind,
    pub remote_idempotency: bool,
    pub verification: VerificationContract,
    pub handler_version: String,
    pub adapter: Option<String>,
    pub require_approval: bool,
    pub automatic_retry: bool,
    pub max_attempts: u32,
}

Immutable execution assumptions recorded before the first attempt.

Contracts are compared before replay, lease acquisition, or execution. Retry delays and timeouts are incidental configuration; the lifetime attempt ceiling is safety relevant and must remain unchanged on reattach. Changing code while retaining handler_version asserts that its external semantics are compatible with this contract.

Fields

format_version: u32

Contract representation version. Currently 1.

kind: EffectKind

What repeating the external operation does.

remote_idempotency: bool

The application attests remote deduplication of the stable key.

verification: VerificationContract

How the runtime may interpret a remote lookup.

handler_version: String

Application-defined semantic version, not a crate release version.

adapter: Option<String>

Optional trusted provider or adapter identity; never a credential.

require_approval: bool

A human decision is required before the first attempt.

automatic_retry: bool

Risk policy permits automatic retries.

max_attempts: u32

Lifetime attempt ceiling, including the initial attempt.

Implementations

impl ExecutionContract

pub fn new(kind: EffectKind, max_attempts: u32) -> Self

Conservative assumptions for an unverified irreversible or reversible operation, with the specified lifetime retry budget.

pub fn permits(&self, requested: &Self) -> bool

Whether requested preserves the recorded execution assumptions. All fields must match; unknown representation versions are refused.
