Module schema

In-memory model of a UCI schema. Enough for the OMS JSON rules; not a full XSD processor.

Build one by hand with the builder methods below, or compile the published XSD into one with crate::xsd::compile.

Structs

• ComplexType
  A named complex type: whether it is abstract, and how it is built.
• Effective
  The facets in force for a type, gathered along its restriction chain.
• Element
  One element declaration: name, type, and occurrence range.
• Facets
  Constraints a simple type places on a value, as written.
• GlobalElement
  A top-level element and the type it is declared as.
• Group
  A run of element declarations under one compositor.
• Pattern
  A pattern facet: what the XSD wrote, and the matcher it translates to.
• Schema
  Enough of a UCI schema to convert and validate OMS JSON.
• SimpleType
  A named simple type: the type it restricts, and the facets it adds.

Enums

• ComplexContent
• GroupKind
• MaxOccurs
  Upper bound of an element declaration. Self::is_array is what conversion uses to decide a JSON array.

Constants

• MAX_SIMPLE_DEPTH 🔒
  How many links of a named-simple-type chain Schema::primitive will follow before giving up. The published schema nests three deep at most; the limit exists so a cyclic hand-built schema cannot hang the caller.

Functions

• choice
  One compositor whose members are alternatives.
• el
  Required once (minOccurs=1, maxOccurs=1).
• el_many
  Zero or more (minOccurs=0, maxOccurs unbounded).
• el_opt
  Optional once (minOccurs=0, maxOccurs=1).
• sequence
  One compositor whose members stand on their own.
• stricter 🔒
  Keep whichever bound is harder to satisfy.
• stricter_f64 🔒
• translate 🔒
  Rewrite an XSD pattern as an equivalent Rust regex.
