Enum Draft 

#[non_exhaustive]
pub enum Draft {
    Draft4,
    Draft6,
    Draft7,
    Draft201909,
    Draft202012,
}

JSON Schema specification versions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Draft

pub fn create_resource(self, contents: Value) -> Resource

Wraps contents in a Resource tagged with this draft version.

pub fn create_resource_ref(self, contents: &Value) -> ResourceRef<'_>

Wraps a reference to contents in a ResourceRef tagged with this draft version.

pub fn from_schema_uri(uri: &str) -> Draft

Detect a draft from a $schema URI string.

Accepts the URI with or without a trailing #. Returns Draft::Unknown for custom/unknown meta-schema URIs.

pub fn detect(self, contents: &Value) -> Draft

Detect what specification could be applied to the given contents.

Inspects the $schema field and returns the matching draft. If no $schema field is present, returns self unchanged — the caller’s current draft is preserved.

Returns Draft::Unknown for custom/unknown $schema values. Validation of custom meta-schemas happens during registry building.

pub const fn id_keyword(self) -> &'static str

Returns the schema identifier keyword used by this draft.

pub fn subresources_of(self, contents: &Value) -> impl Iterator<Item = &Value>

pub fn is_known_keyword(&self, keyword: &str) -> bool

Identifies known JSON schema keywords per draft.

Trait Implementations

impl Clone for Draft

fn clone(&self) -> Draft

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Draft

impl Debug for Draft

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

Formats the value using the given formatter.

impl Default for Draft

fn default() -> Draft

Returns the “default value” for a type.

impl Eq for Draft

impl Hash for Draft

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Draft

fn cmp(&self, other: &Draft) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Draft

fn eq(&self, other: &Draft) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Draft

fn partial_cmp(&self, other: &Draft) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
