SampleId

celestia_types::sample

Struct SampleId 

Source 
pub struct SampleId { /* private fields */ }
Expand description

Identifies a particular Share located in the ExtendedDataSquare.

Implementations§

Source§

impl SampleId

Source

pub fn new(row_index: u16, column_index: u16, block_height: u64) -> Result<Self>

Create a new SampleId for the given row_index and column_index of the ExtendedDataSquare in a block.

§Errors

This function will return an error if the block height is zero.

§Example
use celestia_types::sample::SampleId;

// Consider a 64th share of EDS with block height of 15
let header_height = 15;
SampleId::new(2, 1, header_height).unwrap();
Source

pub fn block_height(&self) -> u64

A height of the block which contains the sample.

Source

pub fn row_index(&self) -> u16

Row index of the ExtendedDataSquare that sample is located on.

Source

pub fn column_index(&self) -> u16

Column index of the ExtendedDataSquare that sample is located on.
