[−][src]Function display_utils::replace_n
pub fn replace_n<'a>(
source: &'a str,
from: &'a str,
to: &'a str,
n: usize
) -> impl Display + 'a
Replace the first n instances of the from
string with the to
string.
Note: this function, contrary to its std equivalent
str::replacen
,
does not support the Pattern API because that API is not yet stabilized.
assert_eq!(replace_n("old old old", "old", "new", 2).to_string(), "new new old");
