Struct FlatSpaces 

pub struct FlatSpaces { /* private fields */ }

The set of flat spaces for a module.

Implementations

impl FlatSpaces

pub fn configure(&mut self, ctx: &Context<'_>)

Learns which spaces are zero-filled. Cheap to call repeatedly: spaces are append-only, so an unchanged count means nothing to redo.

pub fn slot(&mut self, space: MemorySpaceId) -> usize

The stable index of space’s storage, creating it on first use.

Resolve this once and address the space with base_ptr_at thereafter; the index stays valid for the life of these spaces.

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

The base pointer of the storage at slot, grown to hold len bytes.

Panics if slot did not come from slot on these spaces.

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

The base pointer of space’s storage, grown to hold len bytes.

pub fn get(&self, space: MemorySpaceId) -> Option<&FlatSpace>

pub fn entry(&mut self, space: MemorySpaceId) -> &mut FlatSpace

The space’s storage, created on first use.

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

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