FormattingOptions in std::fmt - Rust

pub struct FormattingOptions {  }

Options for formatting.

FormattingOptions is a Formatter without an attached Write trait. It is mainly used to construct Formatter instances.

Construct a new FormatterBuilder with the supplied Write trait object for output that is equivalent to the {} formatting specifier:

• no flags,
• filled with spaces,
• no alignment,
• no width,
• no precision, and
• no DebugAsHex output mode.

Sets or removes the sign (the + or the - flag).

• +: This is intended for numeric types and indicates that the sign should always be printed. By default only the negative sign of signed values is printed, and the sign of positive or unsigned values is omitted. This flag indicates that the correct sign (+ or -) should always be printed.
• -: Currently not used

Sets or unsets the 0 flag.

This is used to indicate for integer formats that the padding to width should both be done with a 0 character as well as be sign-aware

Sets or unsets the # flag.

This flag indicates that the “alternate” form of printing should be used. The alternate forms are:

• Debug : pretty-print the Debug formatting (adds linebreaks and indentation)
• LowerHex as well as UpperHex - precedes the argument with a 0x
• Octal - precedes the argument with a 0b
• Binary - precedes the argument with a 0o

Sets the fill character.

The optional fill character and alignment is provided normally in conjunction with the width parameter. This indicates that if the value being formatted is smaller than width some extra characters will be printed around it.

Sets or removes the alignment.

The alignment specifies how the value being formatted should be positioned if it is smaller than the width of the formatter.

Sets or removes the width.

This is a parameter for the “minimum width” that the format should take up. If the value’s string does not fill up this many characters, then the padding specified by FormattingOptions::fill/FormattingOptions::align will be used to take up the required space.

Sets or removes the precision.

• For non-numeric types, this can be considered a “maximum width”. If the resulting string is longer than this width, then it is truncated down to this many characters and that truncated value is emitted with proper fill, alignment and width if those parameters are set.
• For integral types, this is ignored.
• For floating-point types, this indicates how many digits after the decimal point should be printed.

Specifies whether the Debug trait should use lower-/upper-case hexadecimal or normal integers

Returns the current sign (the + or the - flag).

Returns the current 0 flag.

Returns the current # flag.

Returns the current fill character.

Returns the current alignment.

Returns the current width.

Returns the current precision.

Returns the current precision.
