Struct OSLog 

pub struct OSLog { /* private fields */ }

Safe wrapper around OSLog / os_log_t handles.

Implementations

impl OSLog

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

Creates a log handle for a subsystem/category pair.

Errors

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

pub fn default() -> Self

Returns OSLog.default.

pub fn disabled() -> Self

Returns OSLog.disabled.

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

Returns whether a log level is enabled.

pub fn signposts_enabled(&self) -> bool

Returns whether signposts are enabled for this log handle.

pub fn subsystem(&self) -> Option<String>

Returns the subsystem used to create this log handle, if the bridge knows it.

pub fn category(&self) -> Option<String>

Returns the category used to create this log handle, if the bridge knows it.

Trait Implementations

impl Default for OSLog

fn default() -> Self

Returns the “default value” for a type.

impl Drop for OSLog

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.
