Struct fuel_vm::prelude::MemoryRange

pub struct MemoryRange { /* private fields */ }

Memory range representation for the VM.

start is inclusive, and end is exclusive.

Implementations

impl MemoryRange

pub const fn new(address: Word, size: Word) -> Self

Create a new memory range represented as [address, address + size[.

pub const fn start(&self) -> Word

Beginning of the memory range.

pub const fn end(&self) -> Word

End of the memory range.

pub const fn len(&self) -> Word

Bytes count of this memory range.

pub const fn is_empty(&self) -> bool

Return true if the length is 0.

pub fn boundaries(&self, registers: &OwnershipRegisters) -> (Word, Word)

Return the boundaries of the slice with exclusive end [a, b[

Remap the unbound boundaries to stack or heap when applicable.

pub fn to_heap<S, Tx>(self, vm: &Interpreter<S, Tx>) -> Selfwhere
    Tx: ExecutableTransaction,

Return an owned memory slice with a relative address to the heap space defined in r[$hp]

Trait Implementations

impl Clone for MemoryRange

fn clone(&self) -> MemoryRange

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryRange

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

Formats the value using the given formatter.

impl Default for MemoryRange

fn default() -> Self

Returns the “default value” for a type.

impl<R> From<R> for MemoryRangewhere
    R: RangeBounds<Word>,

fn from(range: R) -> MemoryRange

Converts to this type from the input type.

impl Hash for MemoryRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<MemoryRange> for MemoryRange

fn eq(&self, other: &MemoryRange) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
