Expand description

A glorified callback for executing calls to rustc. Rather than calling rustc directly, we’ll use an Executor, giving clients an opportunity to intercept the build calls.

Required Methods§

source

fn exec( &self, cmd: &ProcessBuilder, id: PackageId, target: &Target, mode: CompileMode, on_stdout_line: &mut dyn FnMut(&str) -> CargoResult<()>, on_stderr_line: &mut dyn FnMut(&str) -> CargoResult<()> ) -> CargoResult<()>

In case of an Err, Cargo will not continue with the build process for this package.

Provided Methods§

source

fn init(&self, _build_runner: &BuildRunner<'_, '_>, _unit: &Unit)

Called after a rustc process invocation is prepared up-front for a given unit of work (may still be modified for runtime-known dependencies, when the work is actually executed).

source

fn force_rebuild(&self, _unit: &Unit) -> bool

Queried when queuing each unit of work. If it returns true, then the unit will always be rebuilt, independent of whether it needs to be.
