Struct JournalEntry 

pub struct JournalEntry {
    pub session_id: SessionId,
    pub call_fingerprint: String,
    pub tool_name: String,
    pub arguments: Value,
    pub result: Value,
    pub is_error: bool,
    pub timestamp_ms: u64,
}

A recorded tool call with its result.

Fields

session_id: SessionId

Session this entry belongs to.

call_fingerprint: String

Deterministic fingerprint of (tool_name + arguments_json).

tool_name: String

Name of the tool that was called.

arguments: Value

Arguments passed to the tool.

result: Value

Recorded result output.

is_error: bool

Whether the original call was an error.

timestamp_ms: u64

Unix epoch milliseconds.

Implementations

impl JournalEntry

pub fn fingerprint(tool_name: &str, arguments: &Value) -> String

Compute a deterministic fingerprint for a tool call.

The fingerprint is stable across restarts and is used for deduplication and idempotent replay.

Trait Implementations

impl Clone for JournalEntry

fn clone(&self) -> JournalEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JournalEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JournalEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for JournalEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
