Union BinaryView 

pub union BinaryView {
    /* private fields */
}

A view over a variable-length binary value.

Either an inlined representation (for values <= 12 bytes) or a reference to an external buffer (for values > 12 bytes).

Implementations

impl BinaryView

pub const MAX_INLINED_SIZE: usize = 12usize

Maximum size of an inlined binary value.

pub fn make_view(value: &[u8], block: u32, offset: u32) -> Self

Create a view from a value, block and offset

Depending on the length of the provided value either a new inlined or a reference view will be constructed.

pub fn empty_view() -> Self

Create a new empty view

pub fn new_inlined(value: &[u8]) -> Self

Create a new inlined binary view

Panics

Panics if the provided string is too long to inline.

pub fn len(&self) -> u32

Returns the length of the binary value.

pub fn is_empty(&self) -> bool

Returns true if the binary value is empty.

pub fn is_inlined(&self) -> bool

Returns true if the binary value is inlined.

pub fn as_inlined(&self) -> &Inlined

Returns the inlined representation of the binary value.

pub fn as_view(&self) -> &Ref

Returns the reference representation of the binary value.

pub fn as_view_mut(&mut self) -> &mut Ref

Returns a mutable reference to the reference representation of the binary value.

pub fn as_u128(&self) -> u128

Returns the binary view as u128 representation.

Trait Implementations

impl Clone for BinaryView

fn clone(&self) -> BinaryView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryView

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

Formats the value using the given formatter.

impl Default for BinaryView

fn default() -> Self

Returns the “default value” for a type.

impl From<Ref> for BinaryView

fn from(value: Ref) -> Self

Converts to this type from the input type.

impl From<u128> for BinaryView

fn from(value: u128) -> Self

Converts to this type from the input type.

impl Hash for BinaryView

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 PartialEq for BinaryView

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.
