Struct Constraints 

pub struct Constraints {

    pub pattern: Option<String>,
    pub min_length: Option<usize>,
    pub max_length: Option<usize>,
    pub minimum: Option<Bound>,
    pub maximum: Option<Bound>,
    pub exclusive_minimum: bool,
    pub exclusive_maximum: bool,

    pub folded_maximum: bool,
    pub multiple_of: Option<Bound>,
    pub min_items: Option<usize>,
    pub max_items: Option<usize>,
    pub unique_items: bool,
    pub min_properties: Option<usize>,
    pub max_properties: Option<usize>,
    pub checked_as: Option<RustType>,
}

The validation keywords a schema declares.

A field with no keyword carries None, so the common schema costs nothing.

Fields

pattern: Option<String>

pattern: the value must match this regular expression.

min_length: Option<usize>

minLength, counted in characters, as JSON Schema counts them.

max_length: Option<usize>

maxLength, counted in characters.

minimum: Option<Bound>

minimum.

maximum: Option<Bound>

maximum.

exclusive_minimum: bool

exclusiveMinimum: makes minimum a strict bound.

exclusive_maximum: bool

exclusiveMaximum: makes maximum a strict bound.

folded_minimum: bool

Whether minimum moved to absorb an exclusiveMinimum.

The bound then holds a number the document does not write, and a message about it must name the number the author wrote instead.

folded_maximum: bool

Whether maximum moved to absorb an exclusiveMaximum.

multiple_of: Option<Bound>

multipleOf.

min_items: Option<usize>

minItems.

max_items: Option<usize>

maxItems.

unique_items: bool

uniqueItems.

min_properties: Option<usize>

minProperties.

max_properties: Option<usize>

maxProperties.

checked_as: Option<RustType>

The type the checks run against, when the field names an alias.

A $ref to a constrained scalar gives the field a named type, and the name alone does not say which check applies. Lowering resolves the ref and records the type behind the name here.

Implementations

impl Constraints

pub fn is_empty(&self) -> bool

Whether the schema declares no keyword at all.

Trait Implementations

impl Clone for Constraints

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraints

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

Formats the value using the given formatter.

impl Default for Constraints

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Constraints

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

Equality operator ==.

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

Inequality operator !=.
