ConsoleLogSubscription

Struct ConsoleLogSubscription 

Source
pub struct ConsoleLogSubscription { /* private fields */ }
Expand description

Unique optional complete-record log subscription.

Implementations§

Source§

impl ConsoleLogSubscription

Source

pub fn write_output(&self, tag: u128, bytes: &[u8]) -> RuntimeResult

Enqueues raw bytes alongside kernel records in publication order.

tag is opaque to the runtime and identifies the application stream and its generation. Adjacent writes with the same tag may coalesce. This operation allocates nothing and never sleeps; a full queue rejects the entire write with WouldBlock and accounts it in dropped().

Source

pub fn try_read(&self) -> Option<ConsoleLogRecord>

Source

pub fn dropped(&self) -> ConsoleLogDropReport

Source

pub fn wait_readable(&self) -> RuntimeResult
