Crate base_traits 

General-purpose traits for generic Rust programming.

The crate supplies small traits for concepts that are useful across unrelated types, including IsEmpty, Len, ToF64, and Zero. Implementations for built-in and standard-library types are controlled by feature flags so consumers can choose the API surface they need.

Example

use base_traits::ToF64;

struct Price(f64);

impl ToF64 for Price {
    fn to_f64(&self) -> f64 {
        self.0
    }
}

let price = Price(12.50);
assert_eq!(12.50, price.to_f64());

The default feature set enables the common built-in and standard-library implementations. The "full" feature enables the broader set, including the experimental process-type implementations. Use "nostd" when the standard library is unavailable.

Traits

AsF64

Trait defining instance method as_f64() : f64 that provides a cost-free conversion into f64.

AsI32

Trait defining instance method as_i32() : i32 that provides a cost-free conversion into i32.

AsI64

Trait defining instance method as_i64() : i64 that provides a cost-free conversion into i64.

AsI128

Trait defining instance method as_i128() : i128 that provides a cost-free conversion into i128.

AsISize

Trait defining instance method as_isize() : isize that provides a cost-free conversion into isize.

AsStr

Trait defining instance method as_str() : &str that allows a type to expose its contiguous character representation to client code.

AsU32

Trait defining instance method as_u32() : u32 that provides a cost-free conversion into u32.

AsU64

Trait defining instance method as_u64() : u64 that provides a cost-free conversion into u64.

AsU128

Trait defining instance method as_u128() : u128 that provides a cost-free conversion into u128.

AsUSize

Trait defining instance method as_usize() : usize that provides a cost-free conversion into usize.

Infinity

Trait defining class method infinity() : T that creates an instance of the implementing type that is conceptually (or actually) infinity.

Integer

IsDefault

Trait defining instance method is_default() : bool that allows a type instance to indicate whether it holds the “default” value.

IsEmpty

Trait defining instance method is_empty() : bool that indicates whether the implementing type instance is logically empty.

IsInfinity

Trait defining instance method is_infinity() : bool that indicates whether the implementing type instance is conceptually (or actually) infinite.

IsNAN

Trait defining instance method is_nan() : bool that indicates whether the implementing type instance has a value that is deemed to be “not a number” (as in so for f32::NAN f64::NAN).

IsZero

Trait defining instance method is_zero() : bool that indicates whether the implementing type instance is numerically zero.

Len

Trait defining instance method len() : usize that indicates whether the implementing type instance is logically empty.

Numeric

Unsigned

Zero

Trait defining class method zero() : T that creates an instance of the implementing type that is conceptually (or actually) zero.
