Trait Implementations

impl Default for WebFetchTool

fn default() -> Self

Returns the “default value” for a type.

impl Tool for WebFetchTool

fn definition(&self) -> &ToolDefinition

Stable borrow of the tool’s definition. Registry calls this once at registration time (for summaries/schema lookup) — implementers typically store a single ToolDefinition in the struct.

fn call<'a>(&'a self, args: Value, ctx: &'a CallContext) -> CallFuture<'a>

Invoke the tool. Args are the deserialized JSON from the wire.

fn supports_pagination(&self) -> bool

SP-pagination-v1 §4.4 — whether this tool’s call_paginated impl produces meaningful pages (cursors emitted on first page, cursors consumed on continuations). Default false: dispatch routes the tool through Binding::call unchanged (preserving CLI / future MCP / REST binding semantics). Tools that override call_paginated must also override this to return true.

fn call_paginated<'a>( &'a self, args: Value, ctx: &'a CallContext, _cursor: Option<&'a str>, ) -> Pin<Box<dyn Future<Output = Result<PaginatedResult, ToolCallError>> + Send + 'a>>

SP-pagination-v1 §4.4 — paginated variant. Default impl wraps call and returns next_cursor: None, so existing tools work unchanged. Tools that want to paginate override this method AND supports_pagination.
