Enum azure_functions::http::Body

pub enum Body<'a> {
    Empty,
    String(Cow<'a, str>),
    Json(Cow<'a, str>),
    Bytes(Cow<'a, [u8]>),
}

Represents the body of a HTTP request or response.

Variants

Empty

Represents an empty body.

String(Cow<'a, str>)

Represents a string body with a default content type of text/plain.

Json(Cow<'a, str>)

Represents a JSON body with a default content type of application/json.

Bytes(Cow<'a, [u8]>)

Represents a body from a slice of bytes with a default content type of application/octet-stream.

Methods

impl<'_> Body<'_>

pub fn default_content_type(&self) -> &str

Gets the default content type for a body.

Returns application/json for Body::Json.

Returns application/octet-stream for Body::Bytes.

Returns text/plain for all other Body values.

Examples

use azure_functions::http::Body;

let body: Body = [1, 2, 3][..].into();

assert_eq!(body.default_content_type(), "application/octet-stream");

pub fn as_str(&self) -> Option<&str>

Gets the body as a string.

Returns None if there is no valid string representation of the message.

Examples

use azure_functions::http::Body;
use std::borrow::Cow;

let body = Body::String(Cow::Borrowed("test"));
assert_eq!(body.as_str().unwrap(), "test");

pub fn as_bytes(&self) -> &[u8]

Gets the body as a slice of bytes.

Examples

use azure_functions::http::Body;
use std::borrow::Cow;

let body = Body::String(Cow::Borrowed("test"));
assert_eq!(body.as_bytes(), "test".as_bytes());

pub fn as_json<'b, T>(&'b self) -> Result<T> where
    T: Deserialize<'b>, 

Deserializes the body as JSON to the requested type.

Examples

use azure_functions::http::Body;
use std::borrow::Cow;

#[derive(Deserialize)]
struct Data {
    message: String
}

let body = Body::String(Cow::Borrowed(r#"{ "message": "hello" }"#));
let data = body.as_json::<Data>().unwrap();
assert_eq!(data.message, "hello");
