Struct ReloadHandle 

pub struct ReloadHandle<T> { /* private fields */ }

A handle to reload a logger inside a ReloadLog.

Implementations

impl<T> ReloadHandle<T>

pub fn replace(&self, logger: T) -> Result<(), ReloadError>

Replace the inner logger.

This replaces the inner logger of the referenced ReloadLog with the given logger, and clears any existing poison from the lock for the inner logger.

Errors

Return ReloadError::Gone if the logger referenced by this reload handle was dropped, and can no longer be reloaded.

pub fn modify<F>(&self, f: F) -> Result<(), ReloadError>

where F: FnOnce(&mut T),

Modify the inner logger.

Call the given function with a mutable reference to the logger. Note that a lock is held while invoking f, so no log messages will be processed until f returns.

If f panics this lock gets poisoned which effectively disables the logger.

Errors

Return ReloadError::Gone if the logger referenced by this reload handle was dropped, and can no longer be reloaded.

Return ReloadError::Poisoned if the reload lock is poisoned.
