Crate efficient_enum [−] [src]

Space-efficient enum values.

For the moment only option types are implemented, as true enums would require something like a const fn version of size_of.

Structs

EfficientOption	An option type similar to `Option<A>`, but where no extra data is used. Instead, some of the space in `A` is used to "tag the union".
EfficientOptionTuple	An option type similar to `(A, Option<B>)`, but where no extra data is used. Instead, some of the space in `A` is used to "tag the union".
TagMSB	A struct represnting the method of tagging using only the `MSB` of a number
Two	A struct for representing enums with 2 options

An enum with 2 options

TagOptions	A trait for getting the number of options associated with a `TaggableValue` of a specific size
TaggableValue	A trait representing a value which can have some space dedicated to use for tagging a union
