Trait DurationArgument 

pub trait DurationArgument: Sealed + Sized {
    // Required methods
    fn require_positive(self, path: &str) -> ArgumentResult<Self>;
    fn require_less_than(self, path: &str, bound: Self) -> ArgumentResult<Self>;
    fn require_at_most(self, path: &str, bound: Self) -> ArgumentResult<Self>;
    fn require_greater_than(
        self,
        path: &str,
        bound: Self,
    ) -> ArgumentResult<Self>;
    fn require_at_least(self, path: &str, bound: Self) -> ArgumentResult<Self>;
}

Validates standard-library duration arguments without losing their unit.

Every successful method returns the original duration. Comparison failures retain both the actual duration and bound as unit-bearing ArgumentValue values.

The trait is sealed and implemented only for Duration.

Required Methods

fn require_positive(self, path: &str) -> ArgumentResult<Self>

Requires this duration to be strictly greater than zero.

Success returns the original duration. A zero duration returns ArgumentErrorKind::Comparison with a GreaterThan(Duration::ZERO) constraint at path.

fn require_less_than(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires this duration to be strictly less than bound.

Success returns the original duration. An unsatisfied comparison returns ArgumentErrorKind::Comparison at path with the exact duration bound.

fn require_at_most(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires this duration to be less than or equal to bound.

Success returns the original duration. An unsatisfied comparison returns ArgumentErrorKind::Comparison at path with the exact duration bound.

fn require_greater_than(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires this duration to be strictly greater than bound.

Success returns the original duration. An unsatisfied comparison returns ArgumentErrorKind::Comparison at path with the exact duration bound.

fn require_at_least(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires this duration to be greater than or equal to bound.

Success returns the original duration. An unsatisfied comparison returns ArgumentErrorKind::Comparison at path with the exact duration bound.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl DurationArgument for Duration

fn require_positive(self, path: &str) -> ArgumentResult<Self>

Requires a nonzero duration and preserves its exact value.

fn require_less_than(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires a duration strictly below the supplied bound.

fn require_at_most(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires a duration at or below the supplied bound.

fn require_greater_than(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires a duration strictly above the supplied bound.

fn require_at_least(self, path: &str, bound: Self) -> ArgumentResult<Self>

Requires a duration at or above the supplied bound.
