def self.new(message : String | Nil = nil, cause : Exception | Nil = nil, *, target = nil)Source

Macro Detail

macro from_errno(message, **opts)Source

Builds an instance of the exception from the current system error value (Errno.value).

The system message corresponding to the OS error value amends the message. Additional keyword arguments are forwarded to the exception initializer .new_from_os_error.

macro from_errno(message = nil, errno = nil, **opts)Source

DEPRECATED Use .from_os_error instead

macro from_winerror(message, **opts)Source

Builds an instance of the exception from the current windows error value (WinError.value).

The system message corresponding to the OS error value amends the message. Additional keyword arguments are forwarded to the exception initializer .new_from_os_error.

macro from_wsa_error(message = nil, **opts)Source

Builds an instance of the exception from the current Windows Socket API error value (WinError.wsa_value).

The system message corresponding to the OS error value amends the message. Additional keyword arguments are forwarded to the exception initializer.
