Struct NodeGetInfoResponse 

pub struct NodeGetInfoResponse {
    pub node_id: String,
    pub max_volumes_per_node: i64,
    pub accessible_topology: Option<Topology>,
}

Fields

node_id: String

The identifier of the node as understood by the SP. This field is REQUIRED. This field MUST contain enough information to uniquely identify this specific node vs all other nodes supported by this plugin. This field SHALL be used by the CO in subsequent calls, including ControllerPublishVolume, to refer to this node. The SP is NOT responsible for global uniqueness of node_id across multiple SPs.

max_volumes_per_node: i64

Maximum number of volumes that controller can publish to the node. If value is not set or zero CO SHALL decide how many volumes of this type can be published by the controller to the node. The plugin MUST NOT set negative values here. This field is OPTIONAL.

accessible_topology: Option<Topology>

Specifies where (regions, zones, racks, etc.) the node is accessible from. A plugin that returns this field MUST also set the VOLUME_ACCESSIBILITY_CONSTRAINTS plugin capability. COs MAY use this information along with the topology information returned in CreateVolumeResponse to ensure that a given volume is accessible from a given node when scheduling workloads. This field is OPTIONAL. If it is not specified, the CO MAY assume the node is not subject to any topological constraint, and MAY schedule workloads that reference any volume V, such that there are no topological constraints declared for V.

Example 1: accessible_topology = {“region”: “R1”, “zone”: “Z2”} Indicates the node exists within the “region” “R1” and the “zone” “Z2”.

Trait Implementations

impl Clone for NodeGetInfoResponse

fn clone(&self) -> NodeGetInfoResponse

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeGetInfoResponse

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NodeGetInfoResponse

fn default() -> Self

Returns the “default value” for a type.

impl Message for NodeGetInfoResponse

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for NodeGetInfoResponse

fn eq(&self, other: &NodeGetInfoResponse) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
