Models the result of “getblocktemplate”

Fields

bits: Vec<u8>

The compressed difficulty in hexadecimal

previous_block_hash: BlockHash

The previous block hash the current template is mining on

current_time: u64

The current time as seen by the server (recommended for block time) Note: this is not necessarily the system clock, and must fall within the mintime/maxtime rules. Expressed as UNIX timestamp.

height: u64

The height of the block we will be mining: current height + 1

sigop_limit: u32

Block sigops limit

size_limit: u32

Block size limit

weight_limit: u32

Block weight limit

version: u32

Block header version

rules: Vec<GetBlockTemplateResultRules>

Block rules that are to be enforced

capabilities: Vec<GetBlockTemplateResultCapabilities>

List of features the Bitcoin Core getblocktemplate implementation supports

version_bits_available: HashMap<u32, String>

Set of pending, supported versionbit (BIP 9) softfork deployments

version_bits_required: u32

Bit mask of versionbits the server requires set in submissions

longpollid: String

Id used in longpoll requests for this template.

transactions: Vec<GetBlockTemplateResultTransaction>

List of transactions included in the template block

signet_challenge: Script

The signet challenge. Only set if mining on a signet, otherwise empty

default_witness_commitment: Script

The default witness commitment included in an OP_RETURN output of the coinbase transactions. Only set when mining on a network where SegWit is activated.

coinbaseaux: HashMap<String, String>

Data that should be included in the coinbase’s scriptSig content. Only the values (hexadecimal byte-for-byte) in this map should be included, not the keys. This does not include the block height, which is required to be included in the scriptSig by BIP 0034. It is advisable to encode values inside “PUSH” opcodes, so as to not inadvertently expend SIGOPs (which are counted toward limits, despite not being executed).

coinbase_value: Amount

Total funds available for the coinbase

target: Vec<u8>

The number which valid hashes must be less than, in big-endian

min_time: u64

The minimum timestamp appropriate for the next block time. Expressed as UNIX timestamp.

mutable: Vec<GetBlockTemplateResulMutations>

List of things that may be changed by the client before submitting a block

nonce_range: Vec<u8>

A range of valid nonces

Trait Implementations

impl Clone for GetBlockTemplateResult

fn clone(&self) -> GetBlockTemplateResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GetBlockTemplateResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GetBlockTemplateResult

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<GetBlockTemplateResult> for GetBlockTemplateResult

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

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

Serialize this value into the given Serde serializer.
