Struct azure_functions::bindings::Blob

pub struct Blob(_);

Represents a Azure Storage blob input or output binding.

Examples

Creating a blob from a string:

use azure_functions::bindings::Blob;

let blob: Blob = "hello world!".into();
assert_eq!(blob.as_str().unwrap(), "hello world!");

Creating a blob from a JSON value (see the json! macro from the serde_json crate):

use azure_functions::bindings::Blob;

let blob: Blob = json!({ "hello": "world!" }).into();

assert_eq!(blob.as_str().unwrap(), r#"{"hello":"world!"}"#);

Creating a blob from a sequence of bytes:

use azure_functions::bindings::Blob;

let blob: Blob = [1, 2, 3][..].into();

assert_eq!(
    blob.as_bytes(),
    [1, 2, 3]
);

Methods

impl Blob

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

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

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

Gets the content of the blob as a slice of bytes.

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

Deserializes the blob as JSON to the requested type.
