Trait tencent_scf::convert::IntoBytes[−][src]

pub trait IntoBytes {
    type Error;
    fn into_bytes(self) -> Result<Vec<u8>, Self::Error>;
}

Trait for converting response into raw bytes.

Custom response should implement this trait so that runtime can send raw bytes to the upstream cloud.

Implement the Trait

One needs to provide a method that can consume the object and produce a byte array.

use tencent_scf::convert::IntoBytes;

// Our custom response type
struct Response(String);

// Simply turn a string into a byte array.
impl IntoBytes for Response {
    type Error = std::convert::Infallible;

    fn into_bytes(self) -> Result<Vec<u8>, Self::Error> {
        Ok(String::into_bytes(self.0))
    }
}

Associated Types

`type Error`[src]

Possible error during the conversion. std::fmt::Display is all the runtime needs.

Required methods

`fn into_bytes(self) -> Result<Vec<u8>, Self::Error>`[src]

Consume the object and serialize it into a byte array.

Implementations on Foreign Types

`impl<T> IntoBytes for Response<T> where Response<T>: TryInto<WebResponse, Error = ResponseEncodeError>,` [src]

This is supported on crate feature builtin-api-gateway only.

Enable auto serialization for Response types

Currently only two types of payload is supported

Response<String>: The body will be treated as a utf-8 string.
Response<Vec<u8>>: The body will be assumed to be binary format. The runtime will perform a base64 encoding to send it to the upstream cloud.
