Struct FlatSpace 

pub struct FlatSpace { /* private fields */ }

One densely-addressed space.

Implementations

impl FlatSpace

pub fn base_ptr(&mut self, len: usize) -> Result<*mut u8, EmulatorErrorKind>

Grows the space so len bytes are addressable, and returns the base pointer of its storage.

For compiled code, which addresses this storage directly rather than through the accessors. The caller must not cause the space to grow while holding the pointer — growing may reallocate — which is why the required size is requested up front.

pub fn read_bytes( &self, addr: u64, size: usize, ) -> Result<Vec<u8>, EmulatorErrorKind>

pub fn read_u128( &self, addr: u64, size: usize, ) -> Result<u128, EmulatorErrorKind>

Reads a little-endian unsigned integer, matching the emulator’s value domain (which is at most 16 bytes wide).

pub fn write_bytes( &mut self, addr: u64, bytes: &[u8], ) -> Result<(), EmulatorErrorKind>

pub fn write_u128( &mut self, addr: u64, size: usize, bits: u128, ) -> Result<(), EmulatorErrorKind>

Writes the low size bytes of a little-endian integer.
