Describes the upper limits on various metrics.

Fields

event_topics: u32

The maximum number of topics supported by an event.

memory_pages: u32

Maximum number of memory pages allowed for a contract.

subject_len: u32

The maximum length of a subject in bytes used for PRNG generation.

payload_len: u32

The maximum size of a storage value and event payload in bytes.

runtime_memory: u32

The maximum node runtime memory. This is for integrity checks only and does not affect the real setting.

validator_runtime_memory: u32

The maximum validator node runtime memory. This is for integrity checks only and does not affect the real setting.

event_ref_time: u64

The additional ref_time added to the deposit_event host function call per event data byte.

Implementations

impl Limits

pub fn max_memory_size(&self) -> u32

The maximum memory size in bytes that a contract can occupy.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Decode for Limits

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

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 Limits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Limits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Limits

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 PartialEq for Limits

fn eq(&self, other: &Limits) -> 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.

impl Serialize for Limits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for Limits

type Identity = Limits

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike for Limits

impl Eq for Limits

impl StructuralPartialEq for Limits
