Enum aws_lambda_events::encodings::Body[−][src]

pub enum Body {
    Empty,
    Text(String),
    Binary(Vec<u8>),
}

Expand description

Representation of http request and response bodies as supported by API Gateway and ALBs.

These come in three flavors

Empty ( no body )
Text ( text data )
Binary ( binary data )

Body types can be Deref and AsRef’d into [u8] types much like the hyper crate

Examples

Body types are inferred with From implementations.

Text

Types like String, str whose type reflects text produce Body::Text variants

assert!(match aws_lambda_events::encodings::Body::from("text") {
  aws_lambda_events::encodings::Body::Text(_) => true,
  _ => false
})

Binary

Types like Vec<u8> and &[u8] whose types reflect raw bytes produce Body::Binary variants

assert!(match aws_lambda_events::encodings::Body::from("text".as_bytes()) {
  aws_lambda_events::encodings::Body::Binary(_) => true,
  _ => false
})

Binary responses bodies will automatically get based64 encoded to meet API Gateway’s response expectations.

Empty

The unit type ( () ) whose type represents an empty value produces Body::Empty variants

assert!(match aws_lambda_events::encodings::Body::from(()) {
  aws_lambda_events::encodings::Body::Empty => true,
  _ => false
})

For more information about API Gateway’s body types, refer to this documentation.

Variants

Empty

An empty body

Text(String)

A body containing string data

Tuple Fields of Text

0: String

Binary(Vec<u8>)

A body containing binary data

Tuple Fields of Binary

0: Vec<u8>

[src]

impl Body

[src]

pub fn from_maybe_encoded(is_base64_encoded: bool, body: &str) -> Body
