Struct ContextStore

pub struct ContextStore { /* private fields */ }

Store of previous message execution context.

Implementations

impl ContextStore

pub fn new( initialized: BTreeSet<ProgramId>, reservation_nonce: ReservationNonce, system_reservation: Option<u64>, local_nonce: u32, ) -> Self

Create a new context store with the provided parameters.

pub fn set_reservation_nonce(&mut self, gas_reserver: &GasReserver)

Set reservation nonce from gas reserver.

Gas reserver has actual nonce state during/after execution.

pub fn add_system_reservation(&mut self, amount: u64)

Set system reservation.

pub fn system_reservation(&self) -> Option<u64>

Get system reservation.

Trait Implementations

impl Clone for ContextStore

fn clone(&self) -> ContextStore

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for ContextStore

fn default() -> ContextStore

Returns the “default value” for a type.

impl Encode for ContextStore

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 ContextStore

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 ContextStore

fn cmp(&self, other: &ContextStore) -> 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 ContextStore

fn eq(&self, other: &ContextStore) -> 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 ContextStore

fn partial_cmp(&self, other: &ContextStore) -> 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.

impl TypeInfo for ContextStore

type Identity = ContextStore

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
