Struct bitcoin::blockdata::locktime::absolute::Height

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

An absolute block height, guaranteed to always contain a valid height value.

Implementations

impl Height

pub const ZERO: Self = _

Absolute block height 0, the genesis block.

pub const MIN: Self = Self::ZERO

The minimum absolute block height (0), the genesis block.

pub const MAX: Self = _

The maximum absolute block height.

pub const fn min_value() -> Self

👎Deprecated since 0.31.0: Use Self::MIN instead

The minimum absolute block height (0), the genesis block.

This is provided for consistency with Rust 1.41.1, newer code should use Height::MIN.

pub const fn max_value() -> Self

👎Deprecated since 0.31.0: Use Self::MAX instead

The maximum absolute block height.

This is provided for consistency with Rust 1.41.1, newer code should use Height::MAX.

pub fn from_consensus(n: u32) -> Result<Height, Error>

Constructs a new block height.

Errors

If n does not represent a block height value (see documentation on LockTime).

Examples

use bitcoin::locktime::absolute::Height;

let h: u32 = 741521;
let height = Height::from_consensus(h).expect("invalid height value");
assert_eq!(height.to_consensus_u32(), h);

pub fn to_consensus_u32(self) -> u32

Converts this Height to its inner u32 value.

Examples

use bitcoin::absolute::LockTime;

let n_lock_time: u32 = 741521;
let lock_time = LockTime::from_consensus(n_lock_time);
assert!(lock_time.is_block_height());
assert_eq!(lock_time.to_consensus_u32(), n_lock_time);

Trait Implementations

Converts to this type from the input type.

impl FromHexStr for Height

type Error = Error

An error occurred while parsing the hex string.

fn from_hex_str_no_prefix<S: AsRef<str> + Into<String>>( s: S ) -> Result<Self, Self::Error>

Parses provided string as hex without requiring 0x prefix.

fn from_hex_str<S: AsRef<str> + Into<String>>( s: S ) -> Result<Self, FromHexError<Self::Error>>

Parses provided string as hex requiring 0x prefix.

impl FromStr for Height

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Height

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Height

fn cmp(&self, other: &Height) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Height> for Height

fn eq(&self, other: &Height) -> 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.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
