Struct Logger 

pub struct Logger { /* private fields */ }

Swift Logger backed by an OSLog handle.

Implementations

impl Logger

pub fn new(subsystem: &str, category: &str) -> Result<Self, LogError>

Creates a logger for a subsystem/category pair.

Errors

Returns an error if either argument contains a NUL byte or the bridge fails.

pub fn from_os_log(log: &OSLog) -> Result<Self, LogError>

Creates a logger from an existing OSLog handle.

Errors

Returns an error if the bridge fails to create the logger wrapper.

pub fn default() -> Self

Returns Logger().

pub fn disabled() -> Self

Returns a disabled logger.

pub fn log(&self, level: Level, message: &str)

Emits a message at one of the classic OSLogType levels.

pub fn log_with_privacy(&self, level: Level, message: &str, privacy: Privacy)

Emits a message with an explicit privacy level.

pub fn trace(&self, message: &str)

pub fn debug(&self, message: &str)

pub fn info(&self, message: &str)

pub fn notice(&self, message: &str)

pub fn warning(&self, message: &str)

pub fn error(&self, message: &str)

pub fn critical(&self, message: &str)

pub fn fault(&self, message: &str)

pub fn is_enabled(&self, level: Level) -> bool

Returns whether the underlying OSLog handle enables this classic level.

pub fn signpost_id(&self) -> OSSignpostId

Generates a signpost identifier associated with this logger’s log handle.

pub fn signpost_id_from_pointer<T>(&self, pointer: *const T) -> OSSignpostId

Generates a signpost identifier derived from a pointer.

pub fn signposts_enabled(&self) -> bool

Returns whether signposts are enabled for this logger’s log handle.

pub fn signpost_event(&self, id: OSSignpostId, name: &str, message: &str)

pub fn signpost_interval_begin(&self, id: OSSignpostId, name: &str)

pub fn signpost_animation_interval_begin(&self, id: OSSignpostId, name: &str)

pub fn signpost_interval_end(&self, id: OSSignpostId, name: &str)

Trait Implementations

impl Default for Logger

fn default() -> Self

Returns the “default value” for a type.

impl Drop for Logger

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
