Block

Implementations

impl Block

pub fn new(cid: Cid, data: Vec<u8>) -> Result<Self, BlockError>

Creates a new block. Returns an error if the hash doesn’t match the data.

pub fn new_unchecked(cid: Cid, data: Vec<u8>) -> Self

Creates a new block without verifying the cid.

pub fn new_data(codec: impl Into<u64>, data: Vec<u8>) -> Self

Create a new block by calculating the Cid from data using the default hasher. Note: The default hasher may changes without notice.

pub fn new_data_digest( digest: impl MultihashDigest<64>, codec: impl Into<u64>, data: Vec<u8>, ) -> Self

Create a new block by calculating the Cid from data.

pub fn cid_data(codec: impl Into<u64>, data: &[u8]) -> Cid

pub fn cid_data_digest( digest: impl MultihashDigest<64>, codec: impl Into<u64>, data: &[u8], ) -> Cid

pub fn cid(&self) -> &Cid

Returns the cid.

pub fn data(&self) -> &[u8]

Returns the payload.

pub fn into_inner(self) -> (Cid, Vec<u8>)

Returns the inner cid and data.

pub fn with_verify(self) -> Result<Block, BlockError>

Block with verified hash.

pub fn with_store_params<P: StoreParams>(self) -> Result<Block, BlockError>

Block with specific store params.

pub fn with_block_max_size( self, max_block_size: usize, ) -> Result<Block, BlockError>

Block with specific store max size.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Hash for Block

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 Block

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Block

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

impl PartialOrd for Block

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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