Trait Key

pub trait Key:
    Eq
    + Hash
    + Send
    + Sync {
    type Extractor;

    // Required method
    fn from_extractor(extractor: &Self::Extractor) -> Self;
}

Trait defining the requirements for a key extractor, which is used to uniquely identify limit subjects and extract rate limit parameters dynamically in request processing.

Required Associated Types

type Extractor

The Extractor associated type represents a component capable of extracting key-specific information from request parts. This information is then used to manage and enforce rate limits dynamically within the application.

Required Methods

fn from_extractor(extractor: &Self::Extractor) -> Self

Creates an instance of Self from the provided extractor reference, allowing extraction of key data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
