pub struct FmtWriter<F1>(_);
Expand description
A writer that calls write_str
for each formatted chunk, but do not require allocations.
Write function can return either ()
or for<E>
Result
<(), E>
.
Writer panics if the write function returns Result::Err
.
Creates a new FmtWriter
from an object that implements WriteStr
.
Creates a new FmtWriter
with a WriteStr
wrapper
deduced with IntoWriteFn
by the closure signature and constructed from it.
