Struct SchemaEngine 

pub struct SchemaEngine { /* private fields */ }

Engine for applying runtime transforms to tool schemas.

Schemars derive generates base schemas at compile time. SchemaEngine applies transforms at runtime for provider flexibility.

Clone behavior

When cloned, custom_transforms are not carried over (they are not Clone). Only per_tool constraints and global_strict settings are cloned.

Implementations

impl SchemaEngine

pub fn new() -> Self

Create a new schema engine.

pub fn with_strict(self, strict: bool) -> Self

Enable strict mode (additionalProperties=false) globally.

pub fn is_strict(&self) -> bool

Get global strict mode setting.

pub fn constrain_field( &mut self, tool: &str, json_path: Vec<String>, c: FieldConstraint, )

Add a field constraint for a specific tool.

The json_path is a list of property names to traverse to reach the field. For example, ["properties", "count"] would target the “count” property.

pub fn add_transform<T: SchemaTransform + 'static>(&mut self, transform: T)

Add a custom transform.

pub fn transform(&self, tool: &str, schema: Schema) -> Schema

Transform a tool’s schema applying all constraints and transforms.

Trait Implementations

impl Clone for SchemaEngine

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for SchemaEngine

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

Formats the value using the given formatter.

impl Default for SchemaEngine

fn default() -> SchemaEngine

Returns the “default value” for a type.
