Struct BlockTime 

pub struct BlockTime(/* private fields */);

A Bitcoin block timestamp.

Each block contains a Unix time timestamp. In addition to serving as a source of variation for the block hash, they also make it more difficult for an adversary to manipulate the block chain.

A timestamp is accepted as valid if it is greater than the median timestamp of previous 11 blocks, and less than the network-adjusted time + 2 hours. “Network-adjusted time” is the median of the timestamps returned by all nodes connected to you. As a result block timestamps are not exactly accurate, and they do not need to be. Block times are accurate only to within an hour or two.

Implementations

impl BlockTime

pub const fn from_u32(t: u32) -> Self

Constructs a new BlockTime from an unsigned 32 bit integer value.

pub const fn to_u32(self) -> u32

Returns the inner u32 value.

impl BlockTime

pub fn from_hex(s: &str) -> Result<Self, PrefixedHexError>

Constructs a new BlockTime from a prefixed hex string.

Errors

If the input string is not a valid hex representation of a blocktime or it does not include the 0x prefix.

pub fn from_unprefixed_hex(s: &str) -> Result<Self, UnprefixedHexError>

Constructs a new BlockTime from an unprefixed hex string.

Errors

If the input string is not a valid hex representation of a blocktime or if it includes the 0x prefix.
