Enum rustc_parse_format::Flag

pub enum Flag {
    FlagSignPlus,
    FlagSignMinus,
    FlagAlternate,
    FlagSignAwareZeroPad,
    FlagDebugLowerHex,
    FlagDebugUpperHex,
}

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.

Trait Implementations

impl Clone for Flag

fn clone(&self) -> Flag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Flag

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

Formats the value using the given formatter.

impl PartialEq<Flag> for Flag

fn eq(&self, other: &Flag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Flag

impl StructuralPartialEq for Flag

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
