Provides utilities to implement Display
, which also provides an "alternate" display.
As an example of using these combinators:
use std::fmt;
use display_container::*;
struct MyItems(Vec<(String, i32)>);
impl fmt::Display for MyItems {
fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
fmt_container(f, "{", "}",
iter_display_chain(
&["magic"],
self.0.iter().map(|(k, v)| display_pair(k, "=", v))
)
)
}
}
Would produce results such as:
{magic, hello=1, world=2}
For "normal" display, produces output like (with prefix="prefix[", suffix="]"
):
prefix[]
prefix[1]
prefix[1, 2]
For "alternate" display, produces output like:
prefix[]
prefix[ 1 ]
prefix[
1,
2
]
This doesn't propagate the flags on the Formatter other than alternate.
