iac_forge::morphism

Struct Identity 

Source 
pub struct Identity<T>(/* private fields */);
Expand description

Identity morphism — useful as a unit in composition chains and as the default transform in pipelines.

Trait Implementations§

Source§

impl<T> Default for Identity<T>

Source§

fn default() -> Self
