Struct CallOpt 

pub struct CallOpt {
    pub timeout: Option<Duration>,
    pub tags: TypeMap,
    pub faststr_tags: FastStrMap,
}

Available on crate feature client only.

Call options for requests

Fields

timeout: Option<Duration>

Timeout of the whole request

This timeout includes connect, sending request headers, receiving response headers, but without receiving streaming data.

tags: TypeMap

Additional information of the endpoint.

Users can use tags to store custom data, such as the datacenter name or the region name, which can be used by the service discoverer.

faststr_tags: FastStrMap

A optimized typemap for storing additional information of the endpoint.

Use FastStrMap instead of TypeMap can reduce the Box allocation.

This is mainly for performance optimization.

Implementations

impl CallOpt

pub fn new() -> Self

Create a new CallOpt.

pub fn set_timeout(&mut self, timeout: Duration)

Set a timeout for the CallOpt.

pub fn with_timeout(self, timeout: Duration) -> Self

Consume current CallOpt and return a new one with the given timeout.

pub fn contains<T: 'static>(&self) -> bool

Check if CallOpt tags contain entry.

pub fn insert<T: Send + Sync + 'static>(&mut self, val: T)

Insert a tag into this CallOpt.

pub fn with<T: Send + Sync + 'static>(self, val: T) -> Self

Consume current CallOpt and return a new one with the tag.

pub fn get<T: 'static>(&self) -> Option<&T>

Get a reference to a tag previously inserted on this CallOpt.

pub fn contains_faststr<T: 'static>(&self) -> bool
