Enum rustc_parse_format::Flag

source · [−]

pub enum Flag {

Expand description

Various flags which can be applied to format strings. The meaning of these flags is defined by the formatters themselves.

Variants

`FlagSignPlus`

A + will be used to denote positive numbers.

`FlagSignMinus`

A - will be used to denote negative numbers. This is the default.

`FlagAlternate`

An alternate form will be used for the value. In the case of numbers, this means that the number will be prefixed with the supplied string.

`FlagSignAwareZeroPad`

For numbers, this means that the number will be padded with zeroes, and the sign (+ or -) will precede them.

`FlagDebugLowerHex`

For Debug / ?, format integers in lower-case hexadecimal.

`FlagDebugUpperHex`

For Debug / ?, format integers in upper-case hexadecimal.
