Struct schemars::gen::SchemaSettings

pub struct SchemaSettings {
    pub option_nullable: bool,
    pub option_add_null_type: bool,
    pub bool_schemas: BoolSchemas,
    pub definitions_path: String,
    pub meta_schema: Option<String>,
    pub allow_ref_siblings: bool,
    /* private fields */
}

Settings to customize how Schemas are generated.

The default settings currently conform to JSON Schema Draft 7, but this is liable to change in a future version of Schemars if support for other JSON Schema versions is added. If you require your generated schemas to conform to draft 7, consider using the draft07 method.

Fields

option_nullable: bool

If true, schemas for Option<T> will include a nullable property.

This is not part of the JSON Schema spec, but is used in Swagger/OpenAPI schemas.

Defaults to false.

option_add_null_type: bool

If true, schemas for Option<T> will have null added to their type.

Defaults to true.

bool_schemas: BoolSchemas

Controls whether trivial Bool schemas may be generated.

Defaults to BoolSchemas::Enabled.

definitions_path: String

A JSON pointer to the expected location of referenceable subschemas within the resulting root schema.

Defaults to "#/definitions/".

meta_schema: Option<String>

The URI of the meta-schema describing the structure of the generated schemas.

Defaults to "http://json-schema.org/draft-07/schema#".

allow_ref_siblings: bool

Whether schemas with a $ref property may have other properties set.

Defaults to false.

Implementations

impl SchemaSettings

pub fn draft07() -> SchemaSettings

Creates SchemaSettings that conform to JSON Schema Draft 7.

pub fn draft2019_09() -> SchemaSettings

Creates SchemaSettings that conform to JSON Schema 2019-09.

pub fn openapi3() -> SchemaSettings

pub fn with(self, configure_fn: impl FnOnce(&mut Self)) -> Self

Modifies the SchemaSettings by calling the given function.

Example

use schemars::gen::{SchemaGenerator, SchemaSettings};

let settings = SchemaSettings::default().with(|s| {
    s.option_nullable = true;
    s.option_add_null_type = false;
});
let gen = settings.into_generator();

pub fn into_generator(self) -> SchemaGenerator

Creates a new SchemaGenerator using these settings.
