Crate token_cell 

This library provides an alternative to ghost-cell which uses concrete types instead of lifetimes for branding.

This allows a more convenient usage, where cells and tokens can be constructed independently, with the same compile-time guarantees as ghost-cell. The trade-off for this arguably more convenient usage and arguably easier to understand branding method is that tokens, while zero-sized if made correctly, must be guaranteed to be constructable only if no other instance exists.

ghost

A traitified version of ghost_cell.

Macros

paste

runtime_token

Produces tokens that are also checked at runtime, ensuring that a TokenCell is never accidentally used with another instance of the same token type.

singleton_token

Produces tokens whose only identifier is their type, but is built such that only one instance of it can exist at any given time.

unsafe_token

Produces tokens whose only identifier is their type.

Structs

RuntimeToken

A small token that’s also checked at runtime, ensuring that a TokenCell is never accidentally used with another instance of the same token type.
