**Kind:** Struct  
**Module:** [log_fastly](https://www.fastly.com/documentation/reference/compute/sdks/rust/log_fastly/)  
**Package:** log-fastly 0.13.1  
**Source:** https://docs.rs/crate/log-fastly/0.13.1/source/src/lib.rs#251

```rust
pub struct Logger { /* private fields */ }
```

An implementation of the [`log::Log`](https://docs.rs/log/0.4.28/log/trait.Log.html) trait for Fastly Compute.

Create and initialize a `Logger` by using the builder returned by [`Logger::builder()`](https://www.fastly.com/documentation/reference/compute/sdks/rust/log_fastly/struct.Logger/#method-builder).

## Methods

### builder

**Source:** https://docs.rs/crate/log-fastly/0.13.1/source/src/lib.rs#298

```rust
fn builder() -> Builder
```

Get a new [`Builder`](https://www.fastly.com/documentation/reference/compute/sdks/rust/log_fastly/struct.Builder/).

**Returns**

`Builder`
