Crate json_schema_ast 

Strict Draft 2020-12 schema documents, validation, and resolved schema IR.

The main entry point is SchemaDocument. Build one from raw JSON with SchemaDocument::from_json, validate instances with SchemaDocument::is_valid, and use compile only when you need direct access to the underlying validator backend. Crates that implement analysis or generation can inspect the lazily resolved canonical IR with SchemaDocument::root.

Structs

ContainsConstraint

Array contains constraints are stored as a single structured value so the count bounds cannot drift out of sync with the subschema itself.

CountRange

Inclusive count range with optional upper bound.

IntegerBounds

A canonical closed interval over signed 64-bit integers.

IntegerMultipleOf

Positive multipleOf constraint stored on integer schemas.

JSONSchema

A compiled JSON Schema validator.

NodeId

Stable identity for one in-memory schema node within the lifetime of the AST.

NumberBounds

A validated floating-point interval with finite endpoints.

NumberMultipleOf

Positive multipleOf constraint stored on number schemas.

PatternConstraint

A pattern constraint with cached matcher state and its original source text.

PatternProperty

One patternProperties entry with both the source pattern and compiled matcher.

SchemaDocument

Fully resolved JSON Schema document.

SchemaNode

Shared immutable representation of a resolved JSON Schema node.

Enums

AstError

CompileError

NumberBound

One finite lower/upper bound for a floating-point interval.

PatternSupport

Whether a regex pattern can be executed by the internal Rust matcher.

SchemaError

SchemaNodeKind

A resolved, executable JSON Schema node.

Functions

compile

Compile a JSON Schema document directly with the validator backend.

json_values_equal

Return true when two JSON values are equal under JSON Schema semantics.

Type Aliases

SchemaBuildError

Public schema-build error name used by SchemaDocument::from_json.
