Abridged version of HostConfiguration (from the Configuration parachains host runtime module) meant to be used by a parachain or PDK such as cumulus.

Fields

max_code_size: u32

The maximum validation code size, in bytes.

max_head_data_size: u32

The maximum head-data size, in bytes.

max_upward_queue_count: u32

Total number of individual messages allowed in the parachain -> relay-chain message queue.

max_upward_queue_size: u32

Total size of messages allowed in the parachain -> relay-chain message queue before which no further messages may be added to it. If it exceeds this then the queue may contain only a single message.

max_upward_message_size: u32

The maximum size of an upward message that can be sent by a candidate.

This parameter affects the size upper bound of the CandidateCommitments.

max_upward_message_num_per_candidate: u32

The maximum number of messages that a candidate can contain.

This parameter affects the size upper bound of the CandidateCommitments.

hrmp_max_message_num_per_candidate: u32

The maximum number of outbound HRMP messages can be sent by a candidate.

This parameter affects the upper bound of size of CandidateCommitments.

validation_upgrade_cooldown: u32

The minimum period, in blocks, between which parachains can update their validation code.

validation_upgrade_delay: u32

The delay, in blocks, before a validation upgrade is applied.

async_backing_params: AsyncBackingParams

Asynchronous backing parameters.

Trait Implementations

impl Clone for AbridgedHostConfiguration

fn clone(&self) -> AbridgedHostConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AbridgedHostConfiguration

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

Formats the value using the given formatter.

impl Decode for AbridgedHostConfiguration

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

where __CodecInputEdqy: Input,

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 Encode for AbridgedHostConfiguration

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

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 AbridgedHostConfiguration

fn eq(&self, other: &AbridgedHostConfiguration) -> 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 TypeInfo for AbridgedHostConfiguration

type Identity = AbridgedHostConfiguration

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike for AbridgedHostConfiguration
