Struct MinUsizeError 

pub struct MinUsizeError<const MIN: usize>(/* private fields */);

This error indicates that a usize value violates the range’s lower bound.

If this crate’s std feature is enabled, this error implements the standard library’s Error trait.

Example

use constrained_int::usize::{ConstrainedUsize, ConstrainedUsizeError};

type Constrained = ConstrainedUsize<1, 254>;

// Lower than the lower bound.
match Constrained::new(0) {
    Err(ConstrainedUsizeError::Lower(err)) => drop(err),
    _ => unreachable!(),
}

Implementations

impl<const MIN: usize> MinUsizeError<MIN>

pub const MIN: usize = MIN

The minimum inclusive bound enforced by the range.

Trait Implementations

impl<const MIN: usize> Clone for MinUsizeError<MIN>

fn clone(&self) -> MinUsizeError<MIN>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const MIN: usize> Display for MinUsizeError<MIN>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const MIN: usize> Error for MinUsizeError<MIN>

Available on crate feature std only.

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<const MIN: usize, const MAX: usize> From<MinUsizeError<MIN>> for ConstrainedUsizeError<MIN, MAX>

fn from(err: MinUsizeError<MIN>) -> Self

Converts to this type from the input type.

impl<const MIN: usize> Hash for MinUsizeError<MIN>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const MIN: usize> Ord for MinUsizeError<MIN>

fn cmp(&self, other: &MinUsizeError<MIN>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<const MIN: usize> PartialEq for MinUsizeError<MIN>

fn eq(&self, other: &MinUsizeError<MIN>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<const MIN: usize> PartialOrd for MinUsizeError<MIN>

fn partial_cmp(&self, other: &MinUsizeError<MIN>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
