Enum fixed_decimal::SignDisplay

#[non_exhaustive]
pub enum SignDisplay {
    Auto,
    Never,
    Always,
    ExceptZero,
    Negative,
}

Configuration for when to render the minus sign or plus sign.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Render the sign according to locale preferences. In most cases, this means a minus sign will be shown on negative numbers, and no sign will be shown on positive numbers.

Never

Do not display the sign. Positive and negative numbers are indistinguishable.

Always

Show a minus sign on negative numbers and a plus sign on positive numbers, including zero.

ExceptZero

Show a minus sign on negative numbers and a plus sign on positive numbers, except do not show any sign on positive or negative zero.

Negative

Show a minus sign on strictly negative numbers. Do not show a sign on positive numbers or on positive or negative zero.

This differs from Auto in that it does not render a sign on negative zero.

Trait Implementations

impl Clone for SignDisplay

fn clone(&self) -> SignDisplay

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignDisplay

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

Formats the value using the given formatter.

impl PartialEq for SignDisplay

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

Tests for self and other values to be equal, and is used by ==.

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

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