Trait Host

}

The process a command line is interpreted for.

Required Methods

fn exists(&self, path: &[u8]) -> bool

Whether path, as this process names it, exists.

fn is_dir(&self, path: &[u8]) -> bool

Whether path, as this process names it, is a directory (symlinks followed).

fn host_path(&self, path: &[u8]) -> Vec<u8>

The absolute host path behind path as this process names it.

A path that does not exist is still mapped, so a binding may name a mount point that appears later.

fn cwd(&self) -> Vec<u8>

The working directory, as this process names it.

fn var(&self, name: &[u8]) -> Option<Vec<u8>>

One environment variable.

fn vars(&self) -> Vec<(Vec<u8>, Vec<u8>)>

The whole environment.

fn read_fd(&self, fd: i32) -> Result<Vec<u8>>

Reads descriptor fd of this process to its end.

fn fd_path(&self, fd: i32) -> Result<Vec<u8>>

The host path descriptor fd of this process is open on.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
