Struct DbBytes 

pub struct DbBytes(/* private fields */);

A cheaply cloneable bytes abstraction for use within the trust boundary of the node (i.e. when interfacing with the database). Serializes and deserializes more efficiently, than most bytes abstractions, but is vulnerable to out-of-memory attacks when read from an untrusted source.

Warning

Do not use this type when deserializing data from an untrusted source!!

Implementations

impl DbBytes

pub fn new(contents: Vec<u8>) -> Self

Create DbBytes from a Vec<u8>

Trait Implementations

impl AsRef<[u8]> for DbBytes

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl BorshDeserialize for DbBytes

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

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

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for DbBytes

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for DbBytes

fn clone(&self) -> DbBytes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbBytes

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

Formats the value using the given formatter.

impl Default for DbBytes

fn default() -> DbBytes

Returns the “default value” for a type.

impl Eq for DbBytes

impl From<Vec<u8>> for DbBytes

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.

impl Ord for DbBytes

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

fn eq(&self, other: &DbBytes) -> 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 DbBytes

fn partial_cmp(&self, other: &DbBytes) -> 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.
