Trait sprintf::Printf

pub trait Printf {
    // Required methods
    fn format(&self, spec: &ConversionSpecifier) -> Result<String>;
    fn as_int(&self) -> Option<i32>;
}

Trait for types that can be formatted using printf strings

Implemented for the basic types and shouldn’t need implementing for anything else.

Required Methods

fn format(&self, spec: &ConversionSpecifier) -> Result<String>

Format self based on the conversion configured in spec.

fn as_int(&self) -> Option<i32>

Get self as an integer for use as a field width, if possible.
