Enum SchemaVersion 

pub enum SchemaVersion {
    Xsd10,
    Xsd11,
    Auto,
}

Which XSD version the compiler should target. XSD 1.1 is a strict superset of 1.0 — every 1.0 schema is also a valid 1.1 schema — so the choice only matters when a schema uses a 1.1-specific construct (xs:assert, xs:alternative, xs:override, wildcard notQName / notNamespace, the 1.1-added built-in datatypes, …).

Defaults to Xsd10 — matches libxml2’s behaviour, matches Xerces and Saxon’s defaults, and avoids the “schema looked like it compiled but the 1.1 constraints aren’t actually being enforced” failure mode that auto-detection produces when authors forget to set vc:minVersion.

Variants

Xsd10

Strict XSD 1.0 — reject any 1.1 construct. Equivalent to libxml2’s behaviour. Recommended for any pipeline that’s migrating from libxml2 or whose schemas predate 2012.

Xsd11

Strict XSD 1.1 — accept 1.1 constructs unconditionally, without requiring vc:minVersion on the schema document.

Auto

Hybrid: start in 1.0 mode, auto-promote to 1.1 when the schema document carries vc:minVersion="1.1" on its root element. Convenient for mixed corpora; explicit opt-in via Xsd11 is still preferred for production pipelines because most 1.1 schemas in the wild don’t bother to set vc:minVersion.

Trait Implementations

impl Clone for SchemaVersion

fn clone(&self) -> SchemaVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SchemaVersion

impl Debug for SchemaVersion

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

Formats the value using the given formatter.

impl Default for SchemaVersion

fn default() -> SchemaVersion

Returns the “default value” for a type.

impl Eq for SchemaVersion

impl PartialEq for SchemaVersion

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