Struct ReplConfig 

pub struct ReplConfig {
    pub script_name: String,
    pub limits: Option<ResourceLimits>,
    pub type_check: bool,
    pub type_check_stubs: Option<String>,
    pub type_check_config: TypeCheckingConfig,

    pub print_flush_interval: Option<Duration>,
    pub os_policy: OsPolicy,
    pub persistence: Persistence,
    pub profile: Option<String>,
}

Arguments for the REPL session a checkout creates — mirrors MontyRepl’s constructor surface.

Fields

script_name: String

Script name used in tracebacks and type-check diagnostics, and the basis of the sandbox’s __file__: its final path component placed under the working directory a feed starts in (/main.py at the root).

limits: Option<ResourceLimits>

Sandbox resource limits enforced inside the worker. None means unlimited (except monty’s standard recursion-depth default).

type_check: bool

Type-check every fed snippet before executing it.

type_check_stubs: Option<String>

Stub declarations made available to type checking.

type_check_config: TypeCheckingConfig

How the worker renders typing diagnostics. Chosen here rather than on the raised error because the structured diagnostics never leave the worker — only the rendered text crosses the wire.

assert_message_annotations: AssertMessageAnnotations

Give failed assert statements pytest-style introspected messages (see limitations/assert.md). On by default with a 120-byte operand-repr truncation; MaxBytes customizes the truncation.

print_flush_interval: Option<Duration>

How long the worker may hold buffered print() output before sending it, batching a burst of prints into one Print event instead of one each. None takes the worker’s default (crate::DEFAULT_PRINT_FLUSH_INTERVAL); Duration::ZERO restores line buffering, delivering each completed line on its own.

Output is always flushed before a suspension or a turn ends, so this only sets how long live output may lag — never what arrives, or in what order. The wire carries whole milliseconds, so a positive interval below 1 ms is sent as 1 ms rather than rounding down into the line-buffering sentinel.

os_policy: OsPolicy

Session clock, initial random state and sleep policy; defaults use the worker’s clock and entropy. CallHost delegates to the caller’s OS handler through TurnEvent::OsCall. System sleeps set system_sleep for the caller to await directly; Zero sleeps return immediately.

persistence: Persistence

Whether a serving relay may store the session; subprocess workers ignore it.

profile: Option<String>

The serving relay’s profile to run the session under; None takes the relay’s default. Subprocess workers ignore it.
