Struct NodeSet 

pub struct NodeSet { /* private fields */ }

A set of cluster node names supporting range notation like node[1-100].

Examples

use consortium::node_set::NodeSet;

let ns = NodeSet::parse("node[1-5,10]").unwrap();
assert_eq!(ns.len(), 6);
assert!(ns.contains("node3"));
assert!(!ns.contains("node7"));

Implementations

impl NodeSet

pub fn new() -> Self

Create an empty NodeSet.

pub fn parse(pattern: &str) -> Result<Self>

Parse a node set from a string like "node[1-10,15],other[001-050]".

pub fn parse_with_autostep(pattern: &str, autostep: Option<u32>) -> Result<Self>

Parse with explicit autostep setting.

pub fn len(&self) -> usize

Number of individual nodes in the set.

pub fn is_empty(&self) -> bool

Whether the set is empty.

pub fn contains(&self, node: &str) -> bool

Check if a specific node name is in the set.

pub fn update(&mut self, other: &NodeSet)

Update (union) this nodeset with another.

pub fn update_str(&mut self, pattern: &str) -> Result<()>

Update from a string pattern.

pub fn union(&self, other: &NodeSet) -> NodeSet

Return the union of this nodeset and another.

pub fn intersection_update(&mut self, other: &NodeSet)

Intersection update: keep only elements in both.

pub fn intersection(&self, other: &NodeSet) -> NodeSet

Return the intersection of this nodeset and another.

pub fn difference_update(&mut self, other: &NodeSet)

Difference update: remove elements of other from self.

pub fn difference(&self, other: &NodeSet) -> NodeSet

Return the difference of this nodeset and another.

pub fn symmetric_difference_update(&mut self, other: &NodeSet)

Symmetric difference update.

pub fn symmetric_difference(&self, other: &NodeSet) -> NodeSet

Return the symmetric difference of this nodeset and another.

pub fn clear(&mut self)

Clear all nodes from this set.

pub fn iter(&self) -> impl Iterator<Item = String> + '_

Iterate all individual node names in sorted order.

pub fn split(&self, nbr: usize) -> Vec<NodeSet>

Split the nodeset into nbr sub-nodesets (at most).

pub fn is_subset(&self, other: &NodeSet) -> bool

Check if this nodeset is a subset of another.

pub fn is_superset(&self, other: &NodeSet) -> bool

Check if this nodeset is a superset of another.

Trait Implementations

impl Clone for NodeSet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeSet

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

Formats the value using the given formatter.

impl Default for NodeSet

fn default() -> Self

Returns the “default value” for a type.

impl Display for NodeSet

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

Formats the value using the given formatter.

impl FromStr for NodeSet

type Err = NodeSetError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.
