Struct tracing_subscriber::fmt::writer::MutexGuardWriter [−][src]
pub struct MutexGuardWriter<'a, W>(_);
fmt
and std
only.Expand description
A type implementing io::Write
for a MutexGuard
where the type
inside the Mutex
implements io::Write
.
This is used by the MakeWriter
implementation for Mutex
, because
MutexGuard
itself will not implement io::Write
— instead, it
dereferences to a type implementing io::Write
. Because MakeWriter
requires the Writer
type to implement io::Write
, it’s necessary to add
a newtype that forwards the trait implementation.
