Struct GitHistoryTool 

pub struct GitHistoryTool;

Tool for investigating file history with actual diffs

Trait Implementations

impl Clone for GitHistoryTool

fn clone(&self) -> GitHistoryTool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Tool for GitHistoryTool

type Args = GitHistoryArgs

Tool execution arguments - ALSO determines output type via ToolArgs::Output.

type Prompts = HistoryPrompts

Prompt provider (MUST be from schema - tools cannot implement PromptProvider).

fn name() -> &'static str

Unique tool name (e.g., “git_clone”)

fn description() -> &'static str

Human-readable description of what this tool does

fn read_only() -> bool

Does this tool only read (never modify) state?

fn destructive() -> bool

Can this tool delete or overwrite existing data?

fn idempotent() -> bool

Is calling this tool repeatedly with same args safe/idempotent?

async fn execute( &self, args: Self::Args, _ctx: ToolExecutionContext, ) -> Result<ToolResponse<<Self::Args as ToolArgs>::Output>, McpError>

Execute the tool with given arguments.

fn validate_schema() -> Result<(), String>

Validate that schema generation works for this tool’s Args type.

fn input_schema() -> Arc<Map<String, Value>>

Input schema - AUTO-GENERATED from Args type via JsonSchema derive Cached for performance - schema is computed once and reused

fn output_schema() -> Arc<Map<String, Value>>

Output schema - AUTO-GENERATED from <Args as ToolArgs>::Output.

fn open_world() -> bool

Does this tool interact with external systems (network, filesystem outside repo)?

fn prompt_name() -> Cow<'static, str>

Prompt name (defaults to “{tool_name}_help”)

fn prompt_description() -> &'static str

Prompt description (defaults to tool description)

fn into_tool_route<S>(self) -> ToolRoute<S>

where S: Send + Sync + 'static,

Convert this tool into an RMCP ToolRoute

fn into_prompt_route<S>(self) -> PromptRoute<S>

where S: Send + Sync + 'static,

Convert this tool into an RMCP PromptRoute

fn arc_into_tool_route<S>(self: Arc<Self>) -> ToolRoute<S>

where S: Send + Sync + 'static,

Convert Arc-wrapped tool into an RMCP ToolRoute (optimized - no extra Arc allocation)

fn arc_into_prompt_route<S>(self: Arc<Self>) -> PromptRoute<S>

where S: Send + Sync + 'static,

Convert Arc-wrapped tool into an RMCP PromptRoute (optimized - no extra Arc allocation)
