Struct pfmt::extras::AdHocFlagsOpts
source · pub struct AdHocFlagsOpts<F>where
F: FnMut(&[String], &[String], &[char], &HashMap<String, String>) -> Result<String, SingleFmtError>,{ /* private fields */ }
Expand description
A wrapper over a closure that accepts full_name
, name
, flags
and
options
parameters of the format
method on Fmt
.
Note that the closure can be FnMut
, not just Fn
.
Also note that while it is possible to call other Fmt
s from the closure,
the args
parameter of the original format
call will be lost and will
have to be replaced somehow by the closure.
