[−][src]Struct azure_functions::bindings::Blob
Represents an Azure Storage blob input or output binding.
The following binding attributes are supported:
Name | Description |
---|---|
name | The name of the parameter being bound. |
path | The path to the blob. |
connection | The name of an app setting that contains the Storage connection string to use for this binding. Defaults to AzureWebJobsStorage . |
Examples
Creating a blob from a string:
use azure_functions::bindings::{HttpRequest, Blob}; use azure_functions::func; #[func] #[binding(name = "output1", path = "example")] pub fn create_blob(_req: HttpRequest) -> ((), Blob) { ((), "Hello world!".into()) }
Creating a blob from a JSON value (see the json! macro from the serde_json
crate):
use azure_functions::bindings::{HttpRequest, Blob}; use azure_functions::func; use serde_json::json; #[func] #[binding(name = "output1", path = "example")] pub fn create_blob(_req: HttpRequest) -> ((), Blob) { ((), json!({ "hello": "world!" }).into()) }
Creating a blob from a sequence of bytes:
use azure_functions::bindings::{HttpRequest, Blob}; use azure_functions::func; #[func] #[binding(name = "output1", path = "example")] pub fn create_blob(_req: HttpRequest) -> ((), Blob) { ((), [1, 2, 3][..].into()) }
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.
