[−][src]Macro writeable::assert_writeable_eq
Testing macro for types implementing Writeable. The first argument should be a string, and
the second argument should be a &dyn Writeable
.
The macro tests for equality of both string content and string length. If your Writeable implementation returns an inexact string length, don't use this macro.
Example
use writeable::Writeable; use writeable::assert_writeable_eq; use std::fmt; struct Demo; impl Writeable for Demo { fn write_to(&self, sink: &mut dyn fmt::Write) -> fmt::Result { sink.write_str("foo") } fn write_len(&self) -> usize { 3 } } assert_writeable_eq!("foo", &Demo);
