Enum IssueCode 

pub enum IssueCode {
    Min,
    Max,
    Length,
    Email,
    Url,
    Uuid,
    Empty,
    Int,
    Positive,
    Finite,
    BoolEquals,
    Coerce,
    Refine,
    TypeMismatch,
    Required,
    Custom(Box<str>),
}

Stable, enumerable identifiers for every builtin constraint (ER-3), plus IssueCode::Custom for consumer-defined ones.

Matchable today; additive variants in minor releases until v1 freezes it, so downstream matches should include a wildcard.

Variants

Min

Value is shorter than the declared minimum length.

Max

Value exceeds the declared maximum length/bound.

Length

Length does not equal the declared exact length.

Email

String does not look like an email address.

Url

String does not look like a URL.

Uuid

String does not look like a UUID.

Empty

String is empty where emptiness is forbidden.

Int

Number has a fractional part where an integer is required.

Positive

Number is zero or negative where positivity is required.

Finite

Float is NaN or infinite where finiteness is required.

BoolEquals

Boolean does not equal the expected value.

Coerce

String-to-type coercion failed.

Refine

A refinement closure rejected the value.

TypeMismatch

Erased-view value has the wrong variant for this schema.

Required

Declared object field is absent from the input object (purely structural: decided by key existence, never by the value found).

Custom(Box<str>)

Consumer-defined constraint identifier, carried verbatim from a RefineRejection.

Builtins never produce this variant; it exists so a consumer running several custom rules can tell them apart. IssueCode::Refine collapses every rule into one code, which defeats keying a translation table off IssueCode. The payload is an opaque consumer namespace: formars neither interprets nor validates it.
