Struct LogFilters 

pub struct LogFilters(/* private fields */);

Parsed and normalized log filters (trimmed, lowercased, deduplicated).

Filters enable selective tracing output via --log flags. An empty set means no filtering (no logs emitted). The set “all” or “*” means all logs emitted. Otherwise, a log message is emitted iff its event name (lowercased) starts with any filter string.

Implementations

impl LogFilters

pub fn new<I, S>(filters: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Create a new LogFilters from filter strings. Entries are trimmed, lowercased, and de-duplicated; empty entries are dropped.

pub fn enabled(&self, event: &str) -> bool

Check if an event should be logged based on these filters.

Returns false if empty (no logs). Returns true if contains “all” or “*”. Otherwise returns true iff the lowercased event name starts with any filter.

pub fn is_empty(&self) -> bool

Check if this filter set is empty (no filters configured).

pub fn as_slice(&self) -> &[String]

Access the underlying filter strings as a slice.
