Module gazebo::prelude

Standard functions. Usually imported with use gazebo::prelude::*.

Contains:

• Extension methods for str and slice/Vec.
• Exports the Dupe trait.
• Defines derive macros such as Dupe_.

The derivation macros appended with underscore are like the normal derivations, but don’t require the trait on any argument types. For example, given the type:

#[derive(Clone_)]
struct Foo<T>(Arc<T>);

It is possible to use derive(Clone), but that would require that T implements Clone, which is unnecessary. Using Clone_ removes that constraint.

Re-exports

pub use crate::dupe::Dupe;

Traits

IterDuped

IterExt

Extension traits on Iterator.

IterOwned

OptionExt

Extension traits on Option where it holds any value or ref.

OptionRefExt

Extension traits on Option where it holds a ref.

SliceClonedExt

Short hand analogous to Iter::cloned, where items of &T are converted to T via clone.

SliceCopiedExt

Short hand analogous to Iter::copied, where items of &T are converted to T via copy.

SliceDupedExt

Short hand analogous to Iter::duped, where items of &T are converted to T via dupe.

SliceExt

Extension traits on slices/Vec.

StrExt

Extension traits on str.

VecExt

Extension traits on Vec.

Copy_

Derive the Copy trait, but without requiring all type arguments to implement Copy.

Default_

Derive the Default trait, but without requiring all type arguments to implement Default.

Dupe

Derive the Dupe trait.
