Struct VarLen

pub struct VarLen;

Varialbe-length integer (used within JSONB).

Trait Implementations

impl BytesRepr for VarLen

const MAX_LEN: usize = 4_294_967_295usize

Maximum length of bytes for this repr (depends on how lenght is stored).

const SIZE: Option<usize> = None

type Ctx = ()

fn serialize(text: &[u8], buf: &mut Vec<u8>)

fn deserialize<'de>( (): Self::Ctx, buf: &mut ParseBuf<'de>, ) -> Result<Cow<'de, [u8]>>

Implementation must check the length of the buffer if Self::SIZE.is_none().

impl Clone for VarLen

fn clone(&self) -> VarLen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarLen

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

Formats the value using the given formatter.

impl Default for VarLen

fn default() -> VarLen

Returns the “default value” for a type.

impl Hash for VarLen

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 IntRepr for VarLen

const SIZE: Option<usize> = None

type Primitive = u32

fn serialize(val: Self::Primitive, buf: &mut Vec<u8>)

fn deserialize(buf: &mut ParseBuf<'_>) -> Result<Self::Primitive>

impl Ord for VarLen

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

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

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