OVSM interpreter errors

Variants§

§

SyntaxError

Syntax error encountered during parsing

Triggered by: Invalid OVSM syntax (missing keywords, malformed expressions) Example: IF $x > 10 (missing THEN keyword)

Fields

§line: usize

Line number where error occurred

§col: usize

Column number where error occurred

§message: String

Error description

§

ParseError(String)

General parse error

§

UnexpectedEof

Unexpected end of file during parsing

§

UnexpectedToken

Unexpected token encountered during parsing

Fields

§expected: String

Expected token description

§got: String

Actual token received

§

UndefinedVariable

Reference to undefined variable

Triggered by: Using a variable before assignment Example: RETURN $x (when $x was never assigned) Prevention: Always initialize variables before use

Fields

§name: String

Variable name

§

UndefinedTool

Reference to undefined tool

Fields

§name: String

Tool name

§

TypeError

Type mismatch error

Triggered by: Operation expecting one type but receiving another Example: $x = "hello" + 5 (string + number), IF "text" THEN (string as boolean) Prevention: Ensure type compatibility in operations and conversions

Fields

§expected: String

Expected type

§got: String

Actual type

§

ConstantReassignment

Attempt to reassign a constant value

Fields

§name: String

Constant name

§

DivisionByZero

Division by zero error

Triggered by: Dividing by zero or taking modulo of zero Example: $x = 10 / 0, $y = 5 % 0 Prevention: Check denominator before division operations

§

IndexOutOfBounds

Array index out of bounds

Triggered by: Accessing array element beyond valid range Example: $arr = [1, 2, 3]; $x = $arr[5] (index 5 when length is 3) Prevention: Check array length before indexing, use LEN() tool

Fields

§index: usize

Requested index

§length: usize

Array length

§

InvalidOperation

Invalid operation for given types

Triggered by: Performing unsupported operations on incompatible types Example: [1,2] * "text" (array multiplication with string) Prevention: Verify operand types support the intended operation

Fields

§op: String

Operation name

§left_type: String

Left operand type

§right_type: String

Right operand type

§

InvalidComparison

Invalid comparison between incompatible types

Fields

§left_type: String

Left operand type

§right_type: String

Right operand type

§

NotCallable

Attempt to call a non-callable value

Fields

§type_name: String

Type of non-callable value

§

EmptyCollection

Operation on empty collection that requires elements

Fields

§operation: String

Operation name

§

ToolExecutionError

Tool execution failed

Triggered by: Runtime failure during tool execution Example: POW(2, 1000000) (computation overflow), SQRT(-5) (negative sqrt) Recovery: Classified as Recoverable - may be retried with different inputs

Fields

§tool: String

Tool name

§reason: String

Failure reason

§

InvalidArguments

Invalid arguments provided to tool

Fields

§tool: String

Tool name

§reason: String

Reason for invalidity

§

NotImplemented

Tool not yet implemented

Fields

§tool: String

Tool name

§

Timeout(Duration)

Operation timed out

§

OutOfMemory(usize)

Memory limit exceeded

§

ExecutionLimitExceeded

Execution limit exceeded

Fields

§limit: usize

Maximum allowed operations

§

TooManyIterations

Too many loop iterations

Fields

§limit: usize

Maximum allowed iterations

§

CircuitOpen

Circuit breaker is open preventing operations

§

InvalidBreak

Break statement used outside of loop

§

InvalidContinue

Continue statement used outside of loop

§

RpcError

RPC call failed

Fields

§message: String

Error message

§

AiServiceError

AI service error

Fields

§message: String

Error message

§

NetworkError

Network operation failed

Fields

§message: String

Error message

§

NoTasksCompleted

No parallel tasks completed successfully

§

UserError(String)

User-defined error
