Struct RetentionPolicy 

pub struct RetentionPolicy {
    pub max_age_days: Option<u64>,
    pub max_runs: Option<usize>,
}

Retention policy for pruning run trace artifact directories.

Fields

max_age_days: Option<u64>

Remove runs older than this many days. None means no age limit.

max_runs: Option<usize>

Keep at most this many runs (newest first). None means no count limit.

Implementations

impl RetentionPolicy

pub fn prune(&self, dir: &Path) -> Result<usize>

Scan <dir>/*/trace.json, apply retention rules, and delete runs that exceed the policy.

Returns the number of pruned entries.

Rules are applied in order:

1. Age: runs with created_at older than max_age_days are deleted.
2. Count: after age pruning, if more than max_runs remain, the oldest are deleted until the count limit is satisfied.
