Struct pfmt::extras::Lazy

pub struct Lazy<T, F>where
    T: Fmt,
    F: FnMut() -> T,{ /* private fields */ }

A wrapper over a closure producing a Fmt.

Note that the closure can be FnMut, not just Fn. Automatically honors any flags, arguments and options the produced Fmt recognizes.

Implementations

impl<T: Fmt, F: FnMut() -> T> Lazy<T, F>

pub fn new(closure: F) -> Self

Trait Implementations

impl<T: Fmt, F: FnMut() -> T> Fmt for Lazy<T, F>

fn format(
    &self,
    full_name: &[String],
    name: &[String],
    args: &[String],
    flags: &[char],
    options: &HashMap<String, String>
) -> Result<String, SingleFmtError>

Call the wrapped closure to get a Fmt, then call format on it.
