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.

Trait Implementations

impl<'a> Arbitrary<'a> for BlockTime

Available on crate feature arbitrary only.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Formats the value using the given formatter.

impl Clone for BlockTime

fn clone(&self) -> BlockTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockTime

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

Formats the value using the given formatter.

impl Decodable for BlockTime

Available on crate feature encoding only.

type Decoder = BlockTimeDecoder

Associated decoder for the type.

fn decoder() -> Self::Decoder

Constructs a “default decoder” for the type.

impl<'de> Deserialize<'de> for BlockTime

Available on crate feature serde only.

fn deserialize<D>(d: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

type Encoder<'e> = BlockTimeEncoder<'e>

The encoder associated with this type. Conceptually, the encoder is like an iterator which yields byte slices.

fn encoder(&self) -> Self::Encoder<'_>

Constructs a “default encoder” for the type.

impl From<BlockTime> for u32

fn from(t: BlockTime) -> Self

Converts to this type from the input type.

fn from(t: u32) -> Self

Converts to this type from the input type.

impl Hash for BlockTime

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for BlockTime

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
