Expand description

A single printf-style formatting directive.

Fields§

§span: &'a str

The entire original formatting directive.

§parameter: Option<u16>

The (1-based) parameter to be converted.

§flags: &'a str

Formatting flags.

§width: Option<Num>

Minimum width of the output.

§precision: Option<Num>

Precision of the conversion.

§length: Option<&'a str>

Length modifier for the conversion.

§type_: &'a str

Type of parameter being converted.

§position: InnerSpan

Byte offset for the start and end of this formatting directive.

Implementations§

source§

impl Format<'_>

source

pub fn translate(&self) -> Result<String, Option<String>>

Translate this directive into an equivalent Rust formatting directive.

Returns Err in cases where the printf directive does not have an exact Rust equivalent, rather than guessing.

impl<'a> PartialEq<Format<'a>> for Format<'a>

source§

fn eq(&self, other: &Format<'a>) -> bool
