  before = NULL
)

Arguments

name: Name of the log (default: getOption("pipfun.log.default"))
event: Type of event to filter (e.g., "info", "warning", "error"). Can be a character vector to match multiple event types.
fun: Optional: function name(s) to filter as a character vector.
after: Optional: filter entries after this datetime. Coerced to POSIXct if needed.
