Expand description

Specification for the formatting of an argument in the format string.

Fields§

§fill: Option<char>

Optionally specified character to fill alignment with.

§fill_span: Option<InnerSpan>

Span of the optionally specified fill character.

§align: Alignment

Optionally specified alignment.

§sign: Option<Sign>

The + or - flag.

§alternate: bool

The # flag.

§zero_pad: bool

The 0 flag.

§debug_hex: Option<DebugHex>

The x or X flag. (Only for Debug.)

§precision: Count<'a>

The integer precision to use.

§precision_span: Option<InnerSpan>

The span of the precision formatting flag (for diagnostics).

§width: Count<'a>

The string width requested for the resulting format.

§width_span: Option<InnerSpan>

The span of the width formatting flag (for diagnostics).

§ty: &'a str

The descriptor string representing the name of the format desired for this argument, this can be empty or any number of characters, although it is required to be one word.

§ty_span: Option<InnerSpan>

The span of the descriptor string (for diagnostics).
