Struct ClientConfig 

pub struct ClientConfig {
    pub base_url: Url,
    pub timeout: Option<Duration>,
    pub retry: Option<RetryPolicy>,
    pub auth: Option<Auth>,
    pub default_headers: HeaderMap,
    pub plugins: Arc<PluginRegistry>,
    pub max_in_flight: Option<Arc<Semaphore>>,
    pub schema_registry: Option<Arc<SchemaRegistry>>,
    pub json_parser: Option<JsonParserFn>,
    pub max_response_bytes: Option<u64>,
    pub retry_body_peek_bytes: u64,
    /* private fields */
}

Shared client configuration (returned by Client::config).

Fields

base_url: Url

Base URL joined with request paths.

timeout: Option<Duration>

Default per-request timeout when the builder does not override it.

retry: Option<RetryPolicy>

Default retry policy for requests that do not set their own.

auth: Option<Auth>

Default authentication applied when a request has no per-request auth.

default_headers: HeaderMap

Headers merged into every request unless overridden.

plugins: Arc<PluginRegistry>

Registered plugins (init hooks + merged hook chains).

max_in_flight: Option<Arc<Semaphore>>

Limits concurrent in-flight requests for this client (including retries).

This is separate from Tower’s ConcurrencyLimitLayer: the client semaphore applies to the full request lifecycle (hooks + retries), while Tower limits only transport-layer concurrency. Avoid stacking both without accounting for that.

schema_registry: Option<Arc<SchemaRegistry>>

Available on crate feature schema only.

Optional strict route registry (feature schema).

json_parser: Option<JsonParserFn>

Available on crate feature json only.

Client-wide custom JSON parser (feature json).

max_response_bytes: Option<u64>

Default maximum response body size for buffered and streaming responses.

retry_body_peek_bytes: u64

Maximum bytes read from a streaming body when evaluating a custom retry predicate.

Implementations

impl ClientConfig

pub fn effective_hooks(&self) -> &Hooks

Hooks executed at runtime (client hooks merged with plugin hooks when the client was built).

This is the chain used for on_request, on_response, and related hooks. The separate hooks field on ClientConfig is the client-only configuration snapshot and is not consulted during requests.

Examples

let client = Client::new("https://api.example.com")?;
let _hooks = client.config().effective_hooks();

Trait Implementations

impl Clone for ClientConfig

fn clone(&self) -> ClientConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.
