pub trait Incrementablewhere
Self: Sized,{
// Required methods
fn increment(&self) -> Option<Self>;
fn initial_value() -> Option<Self>;
}Expand description
A trait representing an incrementable type.
The increment and initial_value functions are fallible.
They should either both return Some with a valid value, or None.
Required Methods§
Sourcefn increment(&self) -> Option<Self>
fn increment(&self) -> Option<Self>
Increments the value.
Returns Some with the incremented value if it is possible, or None if it is not.
Sourcefn initial_value() -> Option<Self>
fn initial_value() -> Option<Self>
Returns the initial value.
Returns Some with the initial value if it is available, or None if it is not.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
