pub trait TrySign {
// Required method
fn try_sign(&self) -> Option<f32>;
// Provided methods
fn is_sign_positive(&self) -> bool { ... }
fn is_sign_negative(&self) -> bool { ... }
}Expand description
A trait for values that can potentially return a sign.
Required Methods§
Provided Methods§
Sourcefn is_sign_positive(&self) -> bool
fn is_sign_positive(&self) -> bool
Returns whether the value is positive. If not possible, returns false.
Sourcefn is_sign_negative(&self) -> bool
fn is_sign_negative(&self) -> bool
Returns whether the value is negative. If not possible, returns false.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
