ToolTargetBuildMode in bootstrap::core::build_steps::tool - Rust
Description: Determines how to build a `ToolTarget`, i.e. which compiler should be used to compile it. The compiler stage is automatically bumped if we need to cross-compile a stage 1 tool.

## ToolTargetBuildMode

# Enum ToolTargetBuildMode

Source

    pub enum ToolTargetBuildMode {
        Build(TargetSelection),
        Dist(Compiler),
    }

Expand description

Determines how to build a `ToolTarget`, i.e. which compiler should be used to compile it. The compiler stage is automatically bumped if we need to cross-compile a stage 1 tool.

## Variants§

§

### Build(TargetSelection)

Build the tool for the given `target` using rustc that corresponds to the top CLI stage.

§

### Dist(Compiler)

Build the tool so that it can be attached to the sysroot of the passed compiler. Since we always dist stage 2+, the compiler that builds the tool in this case has to be stage 1+.

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
