Enum Schema 

#[non_exhaustive]
pub enum Schema {
    Any,
    Null,
    Boolean,
    Number,
    Integer {
        min: i64,

Supported JSON Schema subset, represented without parsing schema text at runtime.

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.

Any

Any bounded JSON value.

Null

Null only.

Boolean

Boolean only.

Number

Any syntactically valid JSON number.

Integer

Signed integer with inclusive bounds.

Fields

min: i64

Inclusive lower bound.

max: i64

Inclusive upper bound.

Unsigned

Unsigned integer with inclusive bounds, retaining all 64 bits.

Fields

min: u64

Inclusive lower bound.

max: u64

Inclusive upper bound.

String

Unicode string, with lengths in Unicode scalar values and optional allowed values.

Fields

min: usize

Minimum character count.

max: usize

Maximum character count.

choices: &'static [&'static str]

Empty accepts any string; otherwise an exact enumeration.

Array

Array whose items all follow one schema.

Fields

items: &'static Schema

Item schema.

min: usize

Minimum number of items.

max: usize

Maximum number of items.

Object

Object with named properties and an explicit policy for unknown names.

Fields

properties: &'static [Property]

Known property definitions.

additional: bool

Whether unknown properties are accepted.

OneOf(&'static [Schema])

Exactly one member schema must match.

Implementations

impl Schema

pub fn validate(&self, value: &Value) -> Result<(), Violation>

Validate a value; unknown properties and missing required members are checked.

pub fn to_json(&self) -> Value

Emit a JSON Schema 2020-12 compatible representation for discovery.

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Schema

impl Debug for Schema

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

Formats the value using the given formatter.
