Struct NegotiatedCapabilities 

pub struct NegotiatedCapabilities { /* private fields */ }

Outcome of a single round of negotiation.

Each entry is (capability name, encoded chosen value). The caller decodes the value via the registered crate::cluster::capability::Capability::decode_value of the matching cap.

Implementations

impl NegotiatedCapabilities

pub fn new() -> Self

Construct an empty result.

pub fn insert(&mut self, name: String, value: Vec<u8>)

Insert or overwrite the chosen value for name.

pub fn get(&self, name: &str) -> Option<&[u8]>

Look up the encoded value picked for name.

pub fn is_empty(&self) -> bool

True when the result holds no entries.

pub fn len(&self) -> usize

Number of negotiated entries.

pub fn iter(&self) -> impl Iterator<Item = (&String, &Vec<u8>)>

Iterate over (name, value-bytes) pairs.

Trait Implementations

impl Clone for NegotiatedCapabilities

fn clone(&self) -> NegotiatedCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NegotiatedCapabilities

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

Formats the value using the given formatter.

impl Default for NegotiatedCapabilities

fn default() -> NegotiatedCapabilities

Returns the “default value” for a type.

impl PartialEq for NegotiatedCapabilities

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