Provided Methods

fn host_open( &self, _filename: Vec<u8>, _flags: HostOpenFlags, _mode: HostMode, ) -> IOResult<u64>

Open a file on the remote stub’s current filesystem.

fn host_close(&self, _fd: u64) -> IOResult<()>

Close a file opened with host_open.

fn host_pread(&self, _fd: u64, _count: u64, _offset: u64) -> IOResult<Vec<u8>>

Read data from an open file at the given offset.

fn host_pwrite(&self, _fd: u64, _offset: u64, _data: Vec<u8>) -> IOResult<u64>

Write data to an open file at the given offset.

fn host_fstat(&self, _fd: u64) -> IOResult<HostStat>

Return a HostStat describing the attributes of the given open file.

fn host_unlink(&self, _filename: Vec<u8>) -> IOResult<()>

Remove a file from the remote stub’s current filesystem.

fn host_readlink(&self, _filename: Vec<u8>) -> IOResult<Vec<u8>>

Read the contents of a symbolic link on the remote stub’s current filesystem.

fn host_setfs(&self, _pid: u64) -> IOResult<()>

Set the current filesystem for subsequent host I/O requests. If the given pid is 0, select the filesystem of the remote stub. Otherwise, select the filesystem as seen by the process with the given pid.

Dyn Compatibility

This trait is dyn compatible.

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