Struct LogConfig 

pub struct LogConfig {
    pub max_sessions: usize,
    pub max_size_mb: u64,
    pub max_age_days: u64,
    pub keep_rotated: usize,
}

Rotation policy for ~/.newt/usage.jsonl.

All limits default to the values shown. Set a field to 0 to disable that particular limit. Multiple active limits compose — the most restrictive one wins after each append.

Example newt.toml:

[logs]
max_sessions = 100   # keep the last 100 turns
max_size_mb  = 5     # also cap at 5 MiB
max_age_days = 14    # and drop anything older than 2 weeks
keep_rotated = 2     # keep usage.jsonl.1 and .2 as backup

Fields

max_sessions: usize

Keep at most this many JSONL entries (most recent). Default: 7. 0 = no limit.

max_size_mb: u64

Rotate when the file exceeds this size in MiB. Default: 0 (no size limit).

max_age_days: u64

Drop entries older than this many days. Default: 0 (no age limit). Requires a recorded_at field in the log entry; entries without it are kept.

keep_rotated: usize

How many rotated copies to keep alongside the live log (usage.jsonl.1, .2, …). Default: 3. 0 = overwrite silently.

Trait Implementations

impl Clone for LogConfig

fn clone(&self) -> LogConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogConfig

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

Formats the value using the given formatter.

impl Default for LogConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogConfig

where LogConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LogConfig

impl PartialEq for LogConfig

fn eq(&self, other: &LogConfig) -> 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.

impl Serialize for LogConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
