Struct cosmwasm_std::BlockInfo

source ·
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

impl PartialEq<BlockInfo> for BlockInfo

source§

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