Struct Height

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

Block height for a particular chain (i.e. number of blocks created since the chain began)

A height of 0 represents a chain which has not yet produced a block.

Implementations

impl Height

pub fn value(&self) -> u64

impl PartialEq for Height

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