variter
is a Rust crate that exports some simple tools for iterating
over enum
types with zero or more variants that have no fields.
```rust use variter::{VarIter, derivevariter}; derivevariter! { #[derive(Debug)] enum Greeting { Hello, Hola, Bonjour, } }
fn main() { for greeting in Greeting::ALL_VARIANTS { println!("{:?}", greeting); } } ```
If you're familiar with the Swift language, it's similar to using the
compiler-synthesized CaseIterable
protocol conformance.
See the module documentation for more information!
Add variter
as a dependency in your Cargo.toml
file:
```toml [dependencies]
variter = "0.2" ```
foreign_impls
(default): include implementions of VarIter
on stable core
types.std
(default): if foreign_impls
is turned on, VarIter
implementations are included for stable std
types.no_std
SupportGiven the simplicity of the crate, no_std
support can be toggled through the
default-features = false
flag in your Cargo.toml
dependency table.
```toml [dependencies]
variter = { version = "0.2", default-features = false } ```
