Struct Servers 

pub struct Servers(/* private fields */);

Wrapper for the servers: field that enforces the invariant of “exactly one datastore” without losing the YAML list shape.

Examples

use dynomite::conf::{ConfServer, Servers};
let s = Servers::from_vec(vec![ConfServer::parse("127.0.0.1:6379:1").unwrap()]);
assert_eq!(s.len(), 1);
assert!(!s.is_empty());
assert!(s.datastore().is_some());

Implementations

impl Servers

pub fn from_vec(v: Vec<ConfServer>) -> Self

Construct from an explicit list. Validation enforces a length of one when called via Config::validate.

Examples

use dynomite::conf::{ConfServer, Servers};
let s = Servers::from_vec(vec![ConfServer::parse("127.0.0.1:6379:1").unwrap()]);
assert_eq!(s.len(), 1);

impl Servers

pub fn entries(&self) -> &[ConfServer]

Borrow the entries.

Examples

use dynomite::conf::{ConfServer, Servers};
let s = Servers::from_vec(vec![ConfServer::parse("127.0.0.1:6379:1").unwrap()]);
assert_eq!(s.entries().len(), 1);

pub fn len(&self) -> usize

Number of entries.

Examples

use dynomite::conf::Servers;
assert_eq!(Servers::default().len(), 0);

pub fn is_empty(&self) -> bool

Whether the list is empty.

Examples

use dynomite::conf::Servers;
assert!(Servers::default().is_empty());

pub fn datastore(&self) -> Option<&ConfServer>

The single datastore (returns the first entry, if any).

Examples

use dynomite::conf::{ConfServer, Servers};
let s = Servers::from_vec(vec![ConfServer::parse("127.0.0.1:6379:1").unwrap()]);
assert!(s.datastore().is_some());
assert!(Servers::default().datastore().is_none());

Trait Implementations

impl Clone for Servers

fn clone(&self) -> Servers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Servers

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

Formats the value using the given formatter.

impl Default for Servers

fn default() -> Servers

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Servers

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Servers

fn eq(&self, other: &Servers) -> 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 Servers

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Servers

impl StructuralPartialEq for Servers
