pub enum Sign {
    Plus,
    Minus,
}
🔬This is a nightly-only experimental API. (formatting_options #118117)

Trait Implementations

Source
impl Clone for Sign
Source
fn clone(&self) -> Sign
Returns a duplicate of the value. Read more
1.0.0Source
fn clone_from(&mut self, source: &Self)
Performs copy-assignment from source. Read more
Source
impl Debug for Sign
Source
fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
Formats the value using the given formatter. Read more
Source
impl PartialEq for Sign
Source
fn eq(&self, other: &Sign) -> bool
Tests for self and other values to be equal, and is used by ==.
1.0.0Source
fn ne(&self, other: &Rhs) -> bool
Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
