Struct OSSignposter 

pub struct OSSignposter { /* private fields */ }

Signpost emitter backed by an OSLog handle.

Implementations

impl OSSignposter

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

Creates a signposter for a subsystem/category pair.

Errors

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

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

Creates a signposter from an OSLog handle.

Errors

Returns an error if the bridge fails.

pub fn from_logger(logger: &Logger) -> Result<Self, LogError>

Creates a signposter from a Logger.

Errors

Returns an error if the bridge fails.

Trait Implementations

impl Default for OSSignposter

fn default() -> Self

Returns the “default value” for a type.

impl Drop for OSSignposter

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.
