Enum ConstraintError 

#[non_exhaustive]
pub enum ConstraintError {
    IsNan(&'static str),
    IsNegative(&'static str),
    IsInfinite(&'static str),
    GrowFixedExclusive,
    MinExceedsMax,
    DeltaNotFinite,
    GridSpanOverflow(usize),
}

Invalid constraint parameter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IsNan(&'static str)

A constraint value is NaN.

IsNegative(&'static str)

A constraint value is negative.

IsInfinite(&'static str)

A constraint value is infinite.

GrowFixedExclusive

Grow and fixed constraints are mutually exclusive.

MinExceedsMax

Minimum exceeds maximum.

DeltaNotFinite

Resize delta must be finite.

GridSpanOverflow(usize)

Grid span overflows u16.

Trait Implementations

impl Debug for ConstraintError

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

Formats the value using the given formatter.

impl Display for ConstraintError

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

Formats the value using the given formatter.

impl Error for ConstraintError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
