Struct SimLogger 

pub struct SimLogger {
    pub entries: Vec<SimLogEntry>,
    pub flush_interval: usize,
    /* private fields */
}

Append-only simulation logger with CSV and JSON serialisation.

Fields

entries: Vec<SimLogEntry>

All logged entries in chronological order.

flush_interval: usize

How many entries to buffer before auto-flushing (0 = manual only).

Implementations

impl SimLogger

pub fn new() -> Self

Create a new logger.

pub fn with_flush_interval(flush_interval: usize) -> Self

Create a logger with an auto-flush interval.

pub fn append(&mut self, entry: SimLogEntry)

Append a new entry.

pub fn len(&self) -> usize

Return the number of logged entries.

pub fn is_empty(&self) -> bool

Returns true if no entries have been logged.

pub fn all_custom_keys(&self) -> Vec<String>

Collect all unique custom field keys across all entries (sorted).

pub fn to_csv(&self) -> String

Serialise all entries to a CSV string.

The first line is a header row. Custom field columns appear in sorted key order.

pub fn to_json(&self) -> String

Serialise all entries to a JSON array string.

pub fn flush(&mut self) -> Vec<String>

Flush buffered lines and return them (clears the buffer).
