Struct ToolError 

pub struct ToolError {
    pub message: String,
}

Error returned when a tool cannot execute at all (infrastructure failure).

Distinguished from ToolOutput::is_error which reports tool-level errors back to the model. A ToolError aborts the agentic loop entirely.

Fields

message: String

Human-readable error message.

Implementations

impl ToolError

pub fn new(message: impl Into<String>) -> Self
