[−][src]Struct azure_functions::bindings::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
[src]
pub fn as_str(&self) -> Option<&str>
[src]
Gets the content of the blob as a string.
Returns None if there is no valid string representation of the blob.
pub fn as_bytes(&self) -> &[u8]
[src]
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>,
[src]
T: Deserialize<'b>,
Deserializes the blob as JSON to the requested type.
