Trait FederationProvider 

pub trait FederationProvider: Send + Sync {
    // Required methods
    fn name(&self) -> &str;
    fn compute_context(&self) -> Option<String>;
    fn optimizer(&self) -> Option<Arc<Optimizer>>;

Required Methods

fn name(&self) -> &str

fn compute_context(&self) -> Option<String>

fn optimizer(&self) -> Option<Arc<Optimizer>>

Trait Implementations

impl Display for dyn FederationProvider

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

Formats the value using the given formatter.

impl Eq for dyn FederationProvider

impl Hash for dyn FederationProvider

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

Feeds this value into the given Hasher.

impl PartialEq for dyn FederationProvider

fn eq(&self, other: &dyn FederationProvider) -> bool

Comparing name, args and return_type

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
