Trait ToCrateName 

pub trait ToCrateName {
    type Output;

    // Required method
    fn to_crate_name(&self) -> Self::Output;
}

Types convertible to the letter casing corresponding to names of crates.

Required Associated Types

type Output

The resulting type, coming out of the conversion.

Required Methods

fn to_crate_name(&self) -> Self::Output

Converts self to the letter casing of crate names (snake_case). Adheres to the general conversion rules.

Examples

Usage with syn::Ident:

let trait_name = Ident::new("DeriveHarvestype", Span::call_site());
let crate_name = trait_name.to_crate_name();
assert_eq!(crate_name, "derive_harvestype");

Usage with strings:

assert_eq!("THE_NEVERHOOD".to_crate_name(), "the_neverhood");
assert_eq!(String::from("AlexAndDerMurder").to_crate_name(), "alex_and_der_murder");

Panics

Whether this method panics depends on the implementator, see their documentation for that. However, implementations from this crate never panic.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
