Struct fadroma::prelude::BlockInfo

pub struct BlockInfo {
    pub height: u64,
    pub time: Timestamp,
    pub chain_id: String,
}

Fields

height: u64

The height of a block is the number of blocks preceding it in the blockchain.

time: Timestamp

Absolute time of the block creation in seconds since the UNIX epoch (00:00:00 on 1970-01-01 UTC).

The source of this is the BFT Time in Tendermint, which has the same nanosecond precision as the Timestamp type.

Examples

Using chrono:

use chrono::NaiveDateTime;
let seconds = env.block.time.seconds();
let nsecs = env.block.time.subsec_nanos();
let dt = NaiveDateTime::from_timestamp(seconds as i64, nsecs as u32);

Creating a simple millisecond-precision timestamp (as used in JavaScript):

let millis = env.block.time.nanos() / 1_000_000;

chain_id: String

Trait Implementations

impl Canonize for BlockInfo

type Output = BlockInfo

fn canonize(self, _api: &dyn Api) -> StdResult<Self::Output>

impl Clone for BlockInfo

fn clone(&self) -> BlockInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockInfo

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

Deserialize this value from the given Serde deserializer.

impl Humanize for BlockInfo

type Output = BlockInfo

fn humanize(self, _api: &dyn Api) -> StdResult<Self::Output>

impl JsonSchema for BlockInfo

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq<BlockInfo> for BlockInfo

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

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

Serialize this value into the given Serde serializer.
