Enum StorageKey 

#[non_exhaustive]
pub enum StorageKey {
    Gas,
    StateHash,
    PageInfo(PageAddr),
    VmSpec,
    VideoMode,
    AudioMode,
    ExecEnvRef,
    Owner,
    ResidentPages,
}

Storage keys used by CoreVM.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Gas

Inner VM gas.

StateHash

The hash of this CoreVM instance.

Computed with corevm_engine::compute_state_hash.

PageInfo(PageAddr)

The last known metadata of a memory page with the specified address.

An instance of PageInfo.

VmSpec

The output data specification of the VM.

An instance of VmSpec.

VideoMode

The current video mode.

An instance of VideoMode.

AudioMode

The current audio mode.

An instance of AudioMode.

ExecEnvRef

Execution environment location in the virtual file system.

The environment (ExecEnv) itself is stored as a file.

Owner

The owner of this CoreVM instance; they can reset the code.

ResidentPages

The pages currently in active use by the program.

Trait Implementations

impl Clone for StorageKey

fn clone(&self) -> StorageKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageKey

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

Formats the value using the given formatter.

impl Encode for StorageKey

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Hash for StorageKey

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 Ord for StorageKey

fn cmp(&self, other: &StorageKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StorageKey

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for StorageKey

fn partial_cmp(&self, other: &StorageKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
