Struct ClientBuilder 

pub struct ClientBuilder { /* private fields */ }

Builder for Client.

Implementations

impl ClientBuilder

pub fn new() -> ClientBuilder

pub fn base_url(self, base_url: impl AsRef<str>) -> Result<ClientBuilder, Error>

pub fn timeout(self, timeout: Duration) -> ClientBuilder

pub fn retry(self, policy: RetryPolicy) -> ClientBuilder

pub fn auth(self, auth: Auth) -> ClientBuilder

pub fn default_header( self, key: impl AsRef<str>, value: impl AsRef<str>, ) -> Result<ClientBuilder, Error>

pub fn hooks(self, hooks: Hooks) -> ClientBuilder

pub fn plugin<P>(self, plugin: P) -> ClientBuilder

where P: Plugin + 'static,

pub fn reqwest_client(self, client: Client) -> ClientBuilder

pub fn backend(self, backend: Arc<dyn HttpBackend>) -> ClientBuilder

Use a custom HTTP backend (for testing or alternate transports).

pub fn max_in_flight(self, limit: usize) -> ClientBuilder

Limits how many requests this client may have in flight at once (including retries).

Implemented with a tokio semaphore in the core client; does not require the tower feature. For token-bucket rate limiting or richer policies, use [Self::transport_stack] with Tower layers (feature tower).

pub fn json_parser<F>(self, f: F) -> ClientBuilder

where F: Fn(&Bytes) -> Result<Value, String> + Send + Sync + 'static,

Sets a custom JSON parser for all responses from this client.

The parser receives raw response bytes and must return a serde_json::Value. Typed deserialization (json, send_json) then uses serde to map that value to T.

pub fn json_parser_fn( self, parser: Arc<dyn Fn(&Bytes) -> Result<Value, String> + Sync + Send>, ) -> ClientBuilder

Sets a custom JSON parser from an existing JsonParserFn.

pub fn build(self) -> Result<Client, Error>

Trait Implementations

impl Default for ClientBuilder

fn default() -> ClientBuilder

Returns the “default value” for a type.
