Enum FunctionCallError 

pub enum FunctionCallError {
    ToolNotFound {
        name: String,
    },
    KindMismatch {
        expected: ToolKind,
        got: ToolKind,
    },
    MutatingToolRejected {
        name: String,
    },
    TimedOut {
        name: String,
        timeout_ms: u64,
    },
    Cancelled {
        name: String,
    },
    ExecutionFailed {
        name: String,
        error: String,
    },
}

Errors that can occur during tool dispatch and execution.

Unlike ToolError, which represents input validation failures within a tool, FunctionCallError covers problems at the dispatch layer: the tool was not found, its kind did not match, it was rejected because it is mutating, it timed out, was cancelled, or its handler returned an error.

Variants

ToolNotFound

No tool with the given name is registered.

Fields

name: String

KindMismatch

The payload kind does not match the handler’s expected kind.

Fields

expected: ToolKind

got: ToolKind

MutatingToolRejected

The tool is mutating but allow_mutating was false.

Fields

name: String

TimedOut

The tool execution exceeded its configured timeout.

Fields

name: String

timeout_ms: u64

Cancelled

The tool execution was cancelled.

Fields

name: String

ExecutionFailed

The tool handler returned an error.

Fields

name: String

error: String
