Function display_utils::replace_n [−][src]
pub fn replace_n<'a, T>(
source: &'a str,
from: &'a str,
to: T,
n: usize
) -> ReplaceN<'a, T> where
T: Display,
Replace the first n instances of the from
string with the to

Note: this function, contrary to its std equivalent
str::replacen
,
does not support the Pattern API because that API is not yet stabilized.
