Struct Reply 

pub struct Reply {
    pub status: u16,
    pub body: Vec<u8>,
    pub error_type: Option<String>,
}

What the control plane answered: a status, a raw body, and the error type the service named, if it named one.

Raw bytes rather than a deserialized value because the error path has to read a body the success types cannot hold, and because TRAP-6’s null message field is only visible to something that did not already require a String there.

Fields

status: u16

body: Vec<u8>

error_type: Option<String>

The x-amzn-ErrorType header’s error name, cut down by error_type_name, or None when the response carried no such header. classify_failure reads it before the status, because the service has sent a throttle as HTTP 400.

Implementations

impl Reply

pub fn json<T: DeserializeOwned>(&self, operation: &str) -> Result<T, Error>

Deserializes the body as T, or reports the failure with the body attached.

The body goes in the message because a rest-json parse failure with the text withheld is unactionable: the reader cannot tell a renamed member from a truncated response. Truncated to 512 bytes, since a list response can be large and the first 512 characters always contain the member that failed.
