Amazonka.SnowDeviceManagement.Types.InstanceState

Description

Synopsis

data InstanceState = InstanceState' {
- name :: Maybe InstanceStateName
- code :: Maybe Int
}
newInstanceState :: InstanceState
instanceState_name :: Lens' InstanceState (Maybe InstanceStateName)
instanceState_code :: Lens' InstanceState (Maybe Int)

Documentation

data InstanceState Source #

The description of the current state of an instance.

See: newInstanceState smart constructor.

Constructors

InstanceState'

Fields

name :: Maybe InstanceStateName
The current state of the instance.
code :: Maybe Int
The state of the instance as a 16-bit unsigned integer.
The high byte is all of the bits between 2^8 and (2^16)-1, which equals decimal values between 256 and 65,535. These numerical values are used for internal purposes and should be ignored.
The low byte is all of the bits between 2^0 and (2^8)-1, which equals decimal values between 0 and 255.
The valid values for the instance state code are all in the range of the low byte. These values are:
- 0 : pending
- 16 : running
- 32 : shutting-down
- 48 : terminated
- 64 : stopping
- 80 : stopped
You can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.

newInstanceState :: InstanceState Source #

Create a value of InstanceState with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:name:InstanceState', instanceState_name - The current state of the instance.

$sel:code:InstanceState', instanceState_code - The state of the instance as a 16-bit unsigned integer.

The high byte is all of the bits between 2^8 and (2^16)-1, which equals decimal values between 256 and 65,535. These numerical values are used for internal purposes and should be ignored.

The low byte is all of the bits between 2^0 and (2^8)-1, which equals decimal values between 0 and 255.

The valid values for the instance state code are all in the range of the low byte. These values are:

0 : pending
16 : running
32 : shutting-down
48 : terminated
64 : stopping
80 : stopped

You can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.

instanceState_name :: Lens' InstanceState (Maybe InstanceStateName) Source #

The current state of the instance.

instanceState_code :: Lens' InstanceState (Maybe Int) Source #

The state of the instance as a 16-bit unsigned integer.

The high byte is all of the bits between 2^8 and (2^16)-1, which equals decimal values between 256 and 65,535. These numerical values are used for internal purposes and should be ignored.

The low byte is all of the bits between 2^0 and (2^8)-1, which equals decimal values between 0 and 255.

The valid values for the instance state code are all in the range of the low byte. These values are:

0 : pending
16 : running
32 : shutting-down
48 : terminated
64 : stopping
80 : stopped

You can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.
