Struct fadroma::ensemble::Block

pub struct Block {
    pub height: u64,
    pub time: u64,
    /* private fields */
}

Fields

height: u64

time: u64

Implementations

impl Block

pub fn exact_increments(&mut self, height: u64, time: u64)

Will increase the block height by height and block time by height * time for each increment.

time is in seconds.

This is the default strategy.

pub fn random_increments(&mut self, height: Range<u64>, time: Range<u64>)

Will increase the block height by a number within the range of height and block time by that same height * time for each increment.

time is in seconds.

pub fn freeze(&mut self)

Will stop incrementing blocks on each message execution and calling next and increment will have no effect.

pub fn unfreeze(&mut self)

Will resume incrementing blocks on each message execution.

pub fn next(&mut self)

Increments the block height and time by the amount configured - once.

Examples

use fadroma::ensemble::Block;
 
let mut block = Block::default();
block.exact_increments(1, 5);
 
let old_height = block.height;
let old_time = block.time;
 
block.next();
 
assert_eq!(block.height - old_height, 1);
assert_eq!(block.time - old_time, 5);
 

pub fn increment(&mut self, times: u64)

Increments the block height and time by the amount configured, multiplied by the times parameter.

Examples

use fadroma::ensemble::Block;

let mut block = Block::default();
block.exact_increments(1, 5);

let old_height = block.height;
let old_time = block.time;

block.increment(3);

assert_eq!(block.height - old_height, 3);
assert_eq!(block.time - old_time, 15);
