Struct Blob 

pub struct Blob<const N: usize> { /* private fields */ }

Variable-size, but limited in capacity byte array.

Implementations

impl<const N: usize> Blob<N>

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

Returns the contents of this array as a byte slice.

pub fn is_empty(&self) -> bool

Returns true if the array is empty.

pub fn len(&self) -> usize

Returns the actual length of this array.

Trait Implementations

impl<const N: usize> AsRef<[u8]> for Blob<N>

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

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

impl<const N: usize> Clone for Blob<N>

fn clone(&self) -> Blob<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for Blob<N>

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

Formats the value using the given formatter.

impl<const N: usize> Default for Blob<N>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: usize> Ord for Blob<N>

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<const N: usize> PartialEq for Blob<N>

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<const N: usize> PartialOrd for Blob<N>

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.

impl<const N: usize> Storable for Blob<N>

const BOUND: Bound

The size bounds of the type.

fn to_bytes(&self) -> Cow<'_, [u8]>

Converts the element into a possibly borrowed byte slice.

fn into_bytes(self) -> Vec<u8>

Converts the element into an owned byte vector.

fn from_bytes(bytes: Cow<'_, [u8]>) -> Self

Converts bytes into an element.

fn to_bytes_checked(&self) -> Cow<'_, [u8]>

Like to_bytes, but checks that bytes conform to declared bounds.

fn into_bytes_checked(self) -> Vec<u8>

where Self: Sized,

Like into_bytes, but checks that bytes conform to declared bounds.

fn check_bounds(bytes: &[u8])

Validates that a byte slice fits within this type’s declared bounds.

impl<const N: usize> TryFrom<&[u8]> for Blob<N>

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
