Implementations

impl DebugLogger

pub fn install_with_max_level( inner: Box<dyn Log>, max_level: LevelFilter, ) -> Result<(), SetLoggerError>

pub fn get() -> &'static Self

pub fn take_captured(&self) -> VecDeque<LogEntry>

pub fn count_matching<F>(&self, predicate: F) -> usize

where F: FnMut(&LogEntry) -> bool,

Counts the number of log entries in the ring buffer which match predicate

pub fn contains_matching<F>(&self, predicate: F) -> bool

where F: FnMut(&LogEntry) -> bool,

Returns true if any entry in the ring buffer matches predicate

pub fn select_matching<F>(&self, predicate: F) -> Vec<LogEntry>

where F: FnMut(&LogEntry) -> bool,

Clones all of the log entries in the buffer which match predicate.

pub fn clone_captured(&self) -> VecDeque<LogEntry>

pub fn init_for_tests() -> Result<(), SetLoggerError>
