Struct astral::thirdparty::slog::Fuse

pub struct Fuse<D>(pub D)
 where
    D: Drain,
    <D as Drain>::Err: Debug;

Drain panicking on error

Logger requires a root drain to handle all errors (Drain::Error == ()), Fuse will wrap a Drain and panic if it returns any errors.

Note: Drain::Err must implement Display (for displaying on panick). It's easy to create own Fuse drain if this requirement can't be fulfilled.

Methods

impl<D> Fuse<D> where
    D: Drain,
    <D as Drain>::Err: Debug, 

pub fn new(drain: D) -> Fuse<D>

Create Fuse wrapping given drain
