One of the XSD built-in datatypes. Simple types defined in user schemas reference one of these as their ultimate base.

Variants

AnySimpleType

XSD §3.16.1 — the ur-simple-type: implicit base of every simple type. Imposes no constraint beyond “is a string”; any post-whitespace lexical value is accepted.

PositiveInteger

DateTimeStamp

Restriction of xs:dateTime requiring a timezone offset (explicitTimezone="required"). Lexical form is identical to xs:dateTime; the only difference is that values without a trailing Z / ±HH:MM are rejected.

DayTimeDuration

Restriction of xs:duration allowing only D / H / M / S components — P1Y and P2M are invalid.

YearMonthDuration

Restriction of xs:duration allowing only Y / M components — P1D, PT1H, etc. are invalid.

AnyAtomicType

Abstract supertype of every atomic primitive (the new intermediate node between xs:anySimpleType and the primitives). Cannot be used to validate an instance directly; only as a base in a restriction chain.

Error

The type whose value space is empty. Every instance value is rejected. Used together with xs:alternative to mark a conditional branch as “this case is an error.”

Implementations

impl BuiltinType

pub fn name(self) -> &'static str

The XSD-spec local name (e.g. "string", "nonNegativeInteger").

pub fn is_xsd11_only(self) -> bool

True for the five built-in types added in XSD 1.1. The schema compiler rejects these as a base= reference when running in strict 1.0 mode.

pub fn default_whitespace(self) -> WhitespaceMode

Default whitespace mode per XSD §3.4.6. string preserves; normalizedString replaces; everything else collapses.

pub fn is_integer_family(self) -> bool

True for xs:integer and the integer subtypes (Long, Int, Short, Byte, NonPositiveInteger, NegativeInteger, NonNegativeInteger, PositiveInteger, UnsignedLong, UnsignedInt, UnsignedShort, UnsignedByte).

pub fn parent(self) -> Option<BuiltinType>

The XSD-spec parent built-in, or None for the 19 primitives that derive directly from xs:anySimpleType. Used by xsi:type derivation checks so a substituted built-in is recognised as a restriction of its declared base (e.g. xs:integer → xs:decimal).

pub fn primitive(self) -> BuiltinType

Walk the parent chain to the spec’s PRIMITIVE built-in (the 19 that derive directly from xs:anySimpleType). Two values of types sharing a primitive ancestor compare equal in the value space — that’s the identity-constraint equality basis per XSD 1.0 §3.11.4 cvc-identity-constraint.4.2.2 / F&O op:numeric-equal, op:string-equal, etc. Self if already a primitive (or a non-derived special like anySimpleType / anyAtomicType / error whose chain stops here).

pub fn derives_from(self, other: BuiltinType) -> bool

True when self derives from other in the built-in hierarchy (including identity). Always a chain of restrictions per XSD §3.16.6.

pub fn from_name(name: &str) -> Option<BuiltinType>

Look up a built-in by its XSD local name (case-sensitive).

Trait Implementations

impl Clone for BuiltinType

fn clone(&self) -> BuiltinType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BuiltinType

impl Debug for BuiltinType

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

Formats the value using the given formatter.

impl Eq for BuiltinType

impl Hash for BuiltinType

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

where __H: Hasher,

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 PartialEq for BuiltinType

fn eq(&self, other: &BuiltinType) -> 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.
