Struct Topology

pub struct Topology {
    pub segments: Option<HashMap<String, String>>,
}

Topology : This description is taken verbatim from the CSI Spec: A topological domain is a sub-division of a cluster, like "region", "zone", "rack", etc. A topological segment is a specific instance of a topological domain, like "zone3", "rack3", etc. For example {"com.company/zone": "Z1", "com.company/rack": "R3"} Valid keys have two segments: an OPTIONAL prefix and name, separated by a slash (/), for example: "com.company.example/zone". The key name segment is REQUIRED. The prefix is OPTIONAL. The key name MUST be 63 characters or less, begin and end with an alphanumeric character ([a-z0-9A-Z]), and contain only dashes (-), underscores (), dots (.), or alphanumerics in between, for example "zone". The key prefix MUST be 63 characters or less, begin and end with a lower-case alphanumeric character ([a-z0-9]), contain only dashes (-), dots (.), or lower-case alphanumerics in between, and follow domain name notation format (https://tools.ietf.org/html/rfc1035#section-2.3.1). The key prefix SHOULD include the plugin’s host company name and/or the plugin name, to minimize the possibility of collisions with keys from other plugins. If a key prefix is specified, it MUST be identical across all topology keys returned by the SP (across all RPCs). Keys MUST be case-insensitive. Meaning the keys "Zone" and "zone" MUST not both exist. Each value (topological segment) MUST contain 1 or more strings. Each string MUST be 63 characters or less and begin and end with an alphanumeric character with ‘-’, ‘’, ‘.’, or alphanumerics in between.

Trait Implementations

impl Clone for Topology

fn clone(&self) -> Topology

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Topology

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

Formats the value using the given formatter.

impl Default for Topology

fn default() -> Topology

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Topology

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Topology

fn eq(&self, other: &Topology) -> 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.

impl Serialize for Topology

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
