Trait Exec 

pub trait Exec {
    // Required method
    fn execve(
        &self,
        path: &CStr,
        args: &[CString],
        envs: &[CString],
    ) -> impl Future<Output = Result<Infallible>> + use<Self>;
}

Trait for executing a new program in the current process

Required Methods

fn execve( &self, path: &CStr, args: &[CString], envs: &[CString], ) -> impl Future<Output = Result<Infallible>> + use<Self>

Replaces the current process with an external utility.

This is a thin wrapper around the execve system call.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Exec for RealSystem

impl Exec for VirtualSystem

impl<T: Exec> Exec for SharedSystem<T>

Delegates Exec methods to the contained implementor.
