Struct UsizeNonZero 

pub struct UsizeNonZero(/* private fields */);

Contract type for non-zero usize values (!= 0).

Validates on construction, then can unwrap to stdlib type via into_inner().

Implementations

impl UsizeNonZero

pub fn new(value: usize) -> Result<Self, ValidationError>

Constructs a non-zero value.

Errors

Returns ValidationError::Zero if value == 0.

pub fn get(&self) -> usize

Gets the wrapped value.

pub fn into_inner(self) -> usize

Unwraps to stdlib type (trenchcoat off).
