# CompilationJob

Struct in [Yarn.Compiler](/3.1/api/csharp/yarn.compiler.md)

Inherits from `System.ValueType`

## Summary

An object that contains Yarn source code to compile, and instructions on how to compile it.

```csharp
public struct CompilationJob
```

## Remarks

Instances of this struct are used with [Compile(CompilationJob)](/3.1/api/csharp/yarn.compiler/yarn.compiler.compiler/yarn.compiler.compiler.compile.md) to produce [CompilationResult](/3.1/api/csharp/yarn.compiler/yarn.compiler.compilationresult.md) objects.
