Struct HostcallRequest 

pub struct HostcallRequest {
    pub call_id: String,
    pub kind: HostcallKind,
    pub payload: Value,
    pub trace_id: u64,
    pub extension_id: Option<String>,
}

A hostcall request enqueued from JavaScript.

Fields

call_id: String

Unique identifier for correlation.

kind: HostcallKind

Type of hostcall.

payload: Value

JSON payload for the hostcall.

trace_id: u64

Trace ID for correlation with macrotask.

extension_id: Option<String>

Active extension id (when known) for policy/log correlation.

Implementations

impl HostcallRequest

pub const fn method(&self) -> &'static str

pub fn required_capability(&self) -> &'static str

pub fn io_uring_capability_class(&self) -> HostcallCapabilityClass

pub fn io_uring_io_hint(&self) -> HostcallIoHint

pub fn io_uring_lane_input( &self, queue_depth: usize, force_compat_lane: bool, ) -> IoUringLaneDecisionInput

pub fn params_for_hash(&self) -> Value

Build the canonical params shape for hashing.

Canonical shapes (must match hostcall_request_to_payload() in extensions.rs):

• tool: { "name": <tool_name>, "input": <payload> }
• exec: { "cmd": <string>, ...payload_fields }
• http: payload passthrough
• session/ui/events: { "op": <string>, ...payload_fields } (flattened)

For non-object args to session/ui/events, payload is preserved under a reserved "payload" key (e.g. { "op": "set_status", "payload": "ready" }).

pub fn params_hash(&self) -> String
