Enum Failure 

pub enum Failure {
    NotACheckout,
    MissingTool {
        tool: &'static str,
        install: &'static str,
    },
    Stage {
        name: &'static str,
        code: Option<i32>,
    },
    Io(String),
}

Why a build did not happen, phrased as the thing to do about it.

Variants

NotACheckout

No book.toml in this directory or any parent.

MissingTool

A tool this needs is not on PATH.

Fields

tool: &'static str

The executable that was not found.

install: &'static str

The command that installs it.

Stage

A stage ran and exited nonzero. Its own output has already been written to the terminal, so this carries no captured text: the compiler’s errors belong on the screen, not inside a JSON string.

Fields

name: &'static str

Which stage.

code: Option<i32>

Its exit code, or None when a signal killed it.

Io(String)

Something failed that is nobody’s fault but the filesystem’s.
