Trait ProviderStrategy 

pub trait ProviderStrategy: Send + Sync {
    // Required method
    fn classify_token_error(
        &self,
        ctx: &ProviderErrorContext,
    ) -> ProviderErrorKind;

    // Provided method
    fn augment_token_request(
        &self,
        _grant: GrantType,
        _form: &mut BTreeMap<String, String>,
    ) { ... }
}

Strategy hook that allows providers to decorate requests and classify errors.

Implementors are required to be Send + Sync, and the hooks intentionally use crate-owned data types so downstream crates never depend on reqwest-specific structures. Override only what you need—augment_token_request has a default no-op implementation.

Required Methods

fn classify_token_error(&self, ctx: &ProviderErrorContext) -> ProviderErrorKind

Maps low-level HTTP/JSON errors into the broker taxonomy for a token request.

Provided Methods

fn augment_token_request( &self, _grant: GrantType, _form: &mut BTreeMap<String, String>, )

Gives providers a chance to add custom form parameters before dispatching.

The default implementation does nothing, which is enough for most providers. Override the hook when a provider requires extra fields (audience, resource, etc.). The method works on a plain BTreeMap so implementations remain HTTP client agnostic.
