Struct ModificationLogEntry 

pub struct ModificationLogEntry {
    pub timestamp: u128,
    pub operation_name: String,
    pub target_id: String,
    pub status: OpStatus,
    pub message: String,
    pub metadata: HashMap<String, String>,
}

A single entry in the modification audit trail.

Each entry captures detailed information about one operation execution, including timing, target, status, and arbitrary metadata.

Fields

timestamp: u128

Timestamp in microseconds since UNIX epoch

operation_name: String

Human-readable name of the operation (e.g., “CreateCausaloid”)

target_id: String

Identifier of the target entity (e.g., causaloid ID, context ID)

status: OpStatus

Whether the operation succeeded or failed

message: String

Descriptive message about the operation result

metadata: HashMap<String, String>

Additional key-value metadata for detailed logging

Implementations

impl ModificationLogEntry

pub fn new( operation_name: impl Into<String>, target_id: impl Into<String>, status: OpStatus, message: impl Into<String>, ) -> Self

Creates a new log entry without a timestamp.

The timestamp will be automatically set when the entry is added to a ModificationLog via add_entry().

Arguments

• operation_name - Name of the operation (e.g., “CreateCausaloid”)
• target_id - ID of the target entity
• status - Success or failure status
• message - Descriptive message

pub fn with_metadata( operation_name: impl Into<String>, target_id: impl Into<String>, status: OpStatus, message: impl Into<String>, metadata: HashMap<String, String>, ) -> Self

Creates a new log entry with metadata.

Arguments

• operation_name - Name of the operation
• target_id - ID of the target entity
• status - Success or failure status
• message - Descriptive message
• metadata - Additional key-value metadata

Trait Implementations

impl Clone for ModificationLogEntry

fn clone(&self) -> ModificationLogEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModificationLogEntry

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

Formats the value using the given formatter.

impl PartialEq for ModificationLogEntry

fn eq(&self, other: &ModificationLogEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
