Struct cosmwasm_std::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 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

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

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::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
