Implementations

impl Value

pub fn new<B>(v: B) -> Value

where B: Into<Bytes>,

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<T: Into<Bytes>> From<Option<T>> for Value

fn from(b: Option<T>) -> Value

Converts to this type from the input type.

impl<T: Into<Bytes>> From<T> for Value

fn from(b: T) -> Value

Converts to this type from the input type.

impl FromCursor for Value

fn from_cursor( cursor: &mut Cursor<&[u8]>, _version: Version ) -> Result<Value, Error>

Tries to parse Self from a cursor of bytes.

impl Hash for Value

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 Ord for Value

fn cmp(&self, other: &Value) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Value

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Value

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

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

Serializes given value using the cursor.

fn serialize_to_vec(&self, version: Version) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.

impl Eq for Value

impl StructuralPartialEq for Value
