core_extensions 0.1.5

This crate provides: - Extension traits for many standard/core library types/traits. - SelfOps:to extend all types with generic operations. - Type-level representations of bool and unsafe . - Marker traits to encode invariants about types. - etc. # no-std support To use this crate in no_std contexts disable the default-feature. # Supported Rust versions This crate support Rust back to 1.20, using a build script to automatically enable features from newer versions. # Cargo Features "std":Enables standard library support.Enabled by default. "serde_":Enables serde support.Disabled by default. "typenum":Enables trait impls for typenum types.Disabled by default.

# **Contents** ## Extension trait:[SelfOps](./trait.SelfOps.html) This is implemented for all types. The most importand methods in this are: - [piped](./trait.SelfOps.html#method.piped): Allows emulating the pipeline operator. - [mutated](./trait.SelfOps.html#method.mutated): Allows mutating `self` with a closure passing it along the method chain - [observe](./trait.SelfOps.html#method.observe): Observes the value of `self` with a closure passing it along the method chain unmodified. - [into_](./trait.SelfOps.html#method.into_), [as_ref_](./trait.SelfOps.html#method.as_ref_), [as_mut_](./trait.SelfOps.html#method.as_mut_): Alternative syntax for the standard conversion methods. ## Other extension traits [ResultExt](./option_result_ext/trait.ResultExt.html)::Extension trait for [Result]. [OptionExt](./option_result_ext/trait.OptionExt.html)::Extension trait for [Option]. [BoolExt](./bool_extensions/trait.BoolExt.html):Extension trait for bool. [IntegerExt](./integer_extensions/trait.IntegerExt.html):Extension trait for integers. [ToTime](./integer_extensions/trait.ToTime.html):Extension trait for integers, to create [Duration](::std::time::Duration)s of a certain unit. [StringExt](./strings/trait.StringExt.html)Extension trait for `str`. ## Marker traits [MarkerType](./marker_traits/trait.MarkerType.html): Represents a zero-sized marker type. ## Other traits [ResultLike](./option_result_ext/trait.ResultLike.html): Trait for types with item/error values,like Option and Result. [TransparentNewtype](./transparent_newtype/trait.TransparentNewtype.html) Represents a newtype that is safe to transmute to and/from its only non-zero-sized field. ## Iteration [IteratorExt](./iterators/trait.IteratorExt.html) Extension trait for [Iterator] implementors. ### Factories [IterCloner](./iterators/struct.IterCloner.html): Constructs [Iterator]s by cloning the one it references,only possible if it is Clone. [IterConstructor](./iterators/struct.IterConstructor.html): Constructs [Iterator]s using a closure,this can be done multiple times if the closure it Copy. ### Iterators [Loop](./iterators/struct.Loop.html): Iterator that infinitely produces a value by calling an impl FnMut()->T [LazyOnce](./iterators/struct.LazyOnce.html): Lazy version of [::std::iter::Once],only evaluating the item when [Iterator::next] is called. ## Type-level stuff ### Type-Level bool This crate contains [types and operations using type-level `bool`s](./type_level_bool/index.html). [Boolean](./type_level_bool/trait.Boolean.html): Trait representing `bool`. [True](./type_level_bool/struct.True.html)/ [False](./type_level_bool/struct.False.html): Types representing `true`/`false`. ### Type equality [TypeIdentity](./trait.TypeIdentity.html) Allows converting a type back to itself.Useful in generic contexts. ### Empty type [Void](./void/enum.Void.html): Uninstantiable Type for statically impossible situations. Useful as a type parameter/associated type. ### (Un)safety represented as type [maybe_unsafe](./maybe_unsafe/index.html) emulates a safe/unsafe effect using types. Allows having traits whose implementations can choose whether their methods/functions are safe to call or not.
