Module xsd 

XML Schema 1.0 — schema compiler and instance validator.

This module is feature-gated behind xsd. The public surface is small:

use sup_xml_core::xsd::Schema;

let schema  = Schema::compile_str(xsd_text)?;
schema.validate_str(instance_xml)?;

See thoughts/xsd_plan.txt in the repo for the full architecture and scope.

Modules

datetime

XSD date/time/duration parsers.

dfa

Deterministic finite automaton for content-model matching.

identity

Identity constraints — <xs:key> / <xs:keyref> / <xs:unique>.

schema

Compiled-schema data structures.

types

Core type-system data structures.

Structs

FacetSet

Set of facets layered on a SimpleType. Empty for the bare built-ins.

FacetViolation

Returned by Facet::check when a facet rejects a value.

FsResolver

Look for schema files on the filesystem relative to a base directory.

InMemoryResolver

Map literal schemaLocation strings to schema bytes held in memory. Useful for embedding schemas in a binary, for tests, or for proxying to an in-process schema cache.

NoResolver

A resolver that always declines. Used by Schema::compile_str for single-file schemas — any <xs:import> or <xs:include> becomes a compile error.

PsviTypes

Post-schema-validation type annotations produced by Schema::validate_doc_typed.

SchemaCompileError

Error returned by Schema::compile_str and friends. Schema compilation produces at most one error — the compiler bails on the first problem since later phases assume a well-formed type graph.

ValidationError

Returned by Schema::validate_str. May contain one or many issues depending on ValidationOptions::fail_fast.

ValidationIssue

One validation problem discovered while walking an instance document.

ValidationOptions

Tunables for Schema::validate_str_opts.

Enums

Facet

One facet constraint. Multiple facets of the same kind on one type are collapsed by the schema compiler into the most-restrictive single value (XSD §4.3 derivation rules).

TimezoneRequirement

Value of the xs:explicitTimezone facet — XSD 1.1 § 4.3.13.

ValidationKind

Categorical tag for a validation issue. Use for programmatic dispatch rather than string-matching the message.

WhitespaceMode

The three whitespace-handling modes defined by XSD §4.3.6.

Traits

SchemaResolver

Resolves a schema-location hint to the XSD bytes for that schema.
