Struct AddressGenerator 

pub struct AddressGenerator {
    next_base_addr: u64,
    end: u64,
}

This provides the logic to generate addresses for memory allocations in a given address range.

Fields

next_base_addr: u64

This is used as a memory address when a new pointer is casted to an integer. It is always larger than any address that was previously made part of a block.

end: u64

This is the last address that can be allocated.

Implementations

impl AddressGenerator

pub fn new(addr_range: Range<u64>) -> Self

pub fn get_remaining(&self) -> Range<u64>

Get the remaining range where this AddressGenerator can still allocate addresses.

pub fn generate<'tcx, R: Rng>( &mut self, size: Size, align: Align, rng: &mut R, ) -> InterpResult<'tcx, u64>

Generate a new address with the specified size and alignment, using the given Rng to add some randomness. The returned allocation is guaranteed not to overlap with any address ranges given out by the generator before. Returns an error if the allocation request cannot be fulfilled.

Trait Implementations

impl Debug for AddressGenerator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
