Struct cardano_multiplatform_lib::byron::Crc32

pub struct Crc32(_);

structure to compute the CRC32 of chunks of bytes.

This structure allows implements the Write trait making it easier to compute the crc32 of a stream.

Implementations

impl Crc32

pub fn to_bytes(&self) -> Vec<u8>

impl Crc32

pub fn from_bytes(bytes: Vec<u8>) -> Result<Crc32, DeserializeError>

impl Crc32

pub fn to_json(&self) -> Result<String, JsError>

pub fn from_json(json: &str) -> Result<Crc32, JsError>

impl Crc32

pub fn from_val(val: u32) -> Crc32

pub fn val(&self) -> u32

impl Crc32

pub fn new() -> Self

initialise a new CRC32 state

pub fn update<'a, I>(&'a mut self, bytes: I) -> &'_ mut Self where
    I: IntoIterator<Item = &'a u8>,

beware that the order in which you update the Crc32 matter.

pub fn finalize(self) -> u32

finalize the CRC32, recovering the computed value

Trait Implementations

impl Clone for Crc32

fn clone(&self) -> Crc32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Crc32

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Crc32

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Deserialize for Crc32

fn deserialize<R: BufRead + Seek>(
    reader: &mut Deserializer<R>
) -> Result<Self, DeserializeError>

impl From<u32> for Crc32

fn from(v: u32) -> Self

Converts to this type from the input type.

impl Hash for Crc32

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, 

Feeds a slice of this type into the given Hasher.

impl JsonSchema for Crc32

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for Crc32

fn cmp(&self, other: &Crc32) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Crc32> for Crc32

fn eq(&self, other: &Crc32) -> 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.

impl PartialOrd<Crc32> for Crc32

fn partial_cmp(&self, other: &Crc32) -> Option<Ordering>

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

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

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

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

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.

impl Serialize for Crc32

fn serialize<'se, W: Write>(
    &self,
    serializer: &'se mut Serializer<W>
) -> Result<&'se mut Serializer<W>>

impl Serialize for Crc32

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl Write for Crc32

fn write(&mut self, bytes: &[u8]) -> Result<usize, Error>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.
