Required methods

fn supports_format(&self, specifier: &Specifier) -> bool

Returns true if self can be formatted using the given specifier.

fn fmt_display(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Display.

fn fmt_debug(&self, f: &mut Formatter<'_>) -> Result

fn fmt_octal(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Octal.

fn fmt_lower_hex(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::LowerHex.

fn fmt_upper_hex(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::UpperHex.

fn fmt_binary(&self, f: &mut Formatter<'_>) -> Result
