Struct kernel::processbuffer::WriteableProcessSlice

#[repr(transparent)]
pub struct WriteableProcessSlice { /* private fields */ }

Read-writeable and accessible slice of memory of a process buffer

The only way to obtain this struct is through a ReadWriteProcessBuffer.

Slices provide a more convenient, traditional interface to process memory. These slices are transient, as the underlying buffer must be checked each time a slice is created. This is usually enforced by the anonymous lifetime defined by the creation of the slice.

Implementations

impl WriteableProcessSlice

pub fn copy_to_slice(&self, dest: &mut [u8])

Copy the contents of a WriteableProcessSlice into a mutable slice reference.

The length of self must be the same as dest. Subslicing can be used to obtain a slice of matching length.

Panics

This function will panic if self.len() != dest.len().

pub fn copy_to_slice_or_err(&self, dest: &mut [u8]) -> Result<(), ErrorCode>

Copy the contents of a WriteableProcessSlice into a mutable slice reference.

The length of self must be the same as dest. Subslicing can be used to obtain a slice of matching length.

pub fn copy_from_slice(&self, src: &[u8])

Copy the contents of a slice of bytes into a WriteableProcessSlice.

The length of src must be the same as self. Subslicing can be used to obtain a slice of matching length.

Panics

This function will panic if src.len() != self.len().

pub fn copy_from_slice_or_err(&self, src: &[u8]) -> Result<(), ErrorCode>

Copy the contents of a slice of bytes into a WriteableProcessSlice.

The length of src must be the same as self. Subslicing can be used to obtain a slice of matching length.
