This type represents an Error.

Implemented traits

AnyType, Copyable, ImplicitlyDestructible, Movable, Writable

Methods

__init__

@implicit __init__(out self, var value: String, *, depth: Int = -1)

Construct an Error object with a given String.

Args:

• ​value (String): The error message.
• ​depth (Int): The depth of the stack trace to collect. When negative, no stack trace is collected.

@implicit __init__(out self, value: StringLiteral[value.value])

Construct an Error object with a given string literal.

Args:

• ​value (StringLiteral): The error message.

@implicit __init__(out self, value: T)

Construct an Error object from a Writable argument.

Args:

• ​value (T): The Writable argument to store in the error message.

__init__[*Ts: Writable](out self, *args: *Ts.values)

Construct an Error by concatenating a sequence of Writable arguments.

Parameters:

• ​*Ts (Writable): The types of the arguments to format. Each type must be satisfy Writable.

Args:

• ​*args (*Ts.values): A sequence of Writable arguments.

write_to

write_to(self, mut writer: T)

Formats this error to the provided Writer.

Args:

• ​writer (T): The object to write to.

write_repr_to

write_repr_to(self, mut writer: T)

Formats this error to the provided Writer.

Args:

• ​writer (T): The object to write to.

get_stack_trace

get_stack_trace(self) -> Optional[String]

Returns the stack trace of the error, if available.

Returns:

Optional: An Optional[String] containing the stack trace if one was collected, or None if stack trace collection was disabled or unavailable.
