Struct cassandra_protocol::types::CBytes

pub struct CBytes { /* fields omitted */ }

The structure that represents Cassandra byte type.

Implementations

impl CBytes

pub fn new(bytes: Vec<u8>) -> CBytes

pub fn new_empty() -> CBytes

Creates Cassandra bytes that represent empty or null value

pub fn into_plain(self) -> Option<Vec<u8>>

Converts CBytes into a plain array of bytes

pub fn as_slice(&self) -> Option<&[u8]>

pub fn is_empty(&self) -> bool

pub fn into_bytes(self) -> Option<Vec<u8>>

Trait Implementations

impl Clone for CBytes

fn clone(&self) -> CBytes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CBytes

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

Formats the value using the given formatter.

impl FromCursor for CBytes

fn from_cursor(cursor: &mut Cursor<&[u8]>) -> CDRSResult<CBytes>

from_cursor gets Cursor who’s position is set such that it should be a start of bytes. It reads required number of bytes and returns a CBytes

impl Hash for CBytes

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 Ord for CBytes

fn cmp(&self, other: &CBytes) -> 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

Restrict a value to a certain interval.

impl PartialEq<CBytes> for CBytes

fn eq(&self, other: &CBytes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &CBytes) -> bool

This method tests for !=.

impl PartialOrd<CBytes> for CBytes

fn partial_cmp(&self, other: &CBytes) -> 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 CBytes

fn serialize(&self, cursor: &mut Cursor<&mut Vec<u8>>)

Serializes given value using the cursor.

fn serialize_to_vec(&self) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.
