Struct SchemaValidator 

pub struct SchemaValidator { /* private fields */ }

Middleware that validates tool call input against the tool’s JSON Schema.

Performs lightweight structural validation: checks that the input is an object, required fields are present, and property types match the schema. This catches obvious input errors before the tool executes, without depending on a full JSON Schema validation library.

Implementations

impl SchemaValidator

pub fn new(registry: &ToolRegistry) -> Self

Create a new schema validator from the current tool registry.

Snapshots all tool definitions at construction time. Tools registered after this call will not be validated.

Trait Implementations

impl ToolMiddleware for SchemaValidator

fn process<'a>( &'a self, call: &'a ToolCall, ctx: &'a ToolContext, next: Next<'a>, ) -> WasmBoxedFuture<'a, Result<ToolOutput, ToolError>>

Process a tool call, optionally delegating to the next middleware/tool.
