Enum ToolCallError 

pub enum ToolCallError {
    NotFound {
        tool_name: String,
    },
    Execution {
        tool_name: String,
        source: ToolError,
    },
}

What can go wrong when the executor calls a tool via the registry.

Two cases only:

• The tool name is not registered (config allows it but nobody registered it)
• The tool is registered but failed during execution

Policy denial is not represented here — that stops the executor before call() is ever invoked.

Variants

NotFound

The tool name was not found in the registry.

Fields

tool_name: String

Execution

The tool was found but failed during execution.

Fields

tool_name: String

source: ToolError
