Trait cargo::core::compiler::Executor[−][src]

pub trait Executor: Send + Sync + 'static {
    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<()>;

    fn init<'a, 'cfg>(&self, _cx: &Context<'a, 'cfg>, _unit: &Unit<'a>) { ... }

    fn force_rebuild(&self, _unit: &Unit<'_>) -> bool { ... }
}

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

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<()>[src]

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

Provided methods

fn init<'a, 'cfg>(&self, _cx: &Context<'a, 'cfg>, _unit: &Unit<'a>)[src]

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).

fn force_rebuild(&self, _unit: &Unit<'_>) -> bool[src]

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.
