Implementations

impl SpecVersion

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

Returns the canonical meta-schema URI for this draft (e.g. for use in $schema).

URIs match the local specs (draft-00 through 2020-12). Drafts 00–02 used hyper-schema URIs; draft-03 onward use schema# or draft/YYYY-MM/schema.

pub fn from_schema_uri(s: &str) -> Option<SpecVersion>

Parses a $schema URI string and returns the corresponding SpecVersion, if recognized.

Matching is done by comparing the trimmed string to canonical URIs (with or without trailing slash). The legacy draft-04 URI http://json-schema.org/schema# is deprecated and returns [Some(SpecVersion::Draft04)] for compatibility.

Returns None for empty, unknown, or malformed URIs.

pub fn default_schema_settings(self) -> JsonSchemaSettings

Returns JsonSchemaSettings tuned for this spec version. Callers can use the builder to override individual options.

Default (latest) spec: Draft202012 is the latest supported spec; its settings match JsonSchemaSettings::default() when no options are set.

Trait Implementations

impl Clone for SpecVersion

fn clone(&self) -> SpecVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecVersion

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

Formats the value using the given formatter.

impl PartialEq for SpecVersion

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