Enum SelectParams 

pub enum SelectParams {
    Random {
        n: u32,
    },
    NearKey {
        key: Vec<u8>,
        n: u32,
    },
    All,
}

Parameters describing what peer set to select. Different concrete selectors handle the variants they support and return an error variant for the ones they don’t (e.g. GlobalRegistry supports Random + All; DhtView supports NearKey).

Open enum - new variants are additive; concrete impls match the ones they handle + return an unsupported-params error for the rest.

Variants

Random

Sample n peers uniformly at random from the current view.

Fields

n: u32

Number of peers requested.

NearKey

Sample up to n peers whose identifier is closest to key under whatever metric the selector uses (Kademlia XOR, etc.).

Fields

key: Vec<u8>

Routing key the selector matches against.

n: u32

Maximum peers to return.

All

Return every peer in the current view. Useful for tiny fixed-size deployments + tests.

Trait Implementations

impl Clone for SelectParams

fn clone(&self) -> SelectParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectParams

fn deserialize<__D>( __deserializer: __D, ) -> Result<SelectParams, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SelectParams

impl Hash for SelectParams

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SelectParams

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
