Struct RawValue

pub struct RawValue<V>
where
    V: Value,
{ /* private fields */ }

Available on crate feature provider only.

Raw table value.

Implementations

impl<V> RawValue<V>

where V: Value,

pub fn new(value: V) -> RawValue<V>

Create new raw value.

pub const fn from_vec(vec: Vec<u8>) -> RawValue<V>

Creates a raw value from an existing Vec. Useful when we already have the encoded value.

pub fn value(&self) -> Result<V, DatabaseError>

Returns the decompressed value.

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

Returns the raw value as seen on the database.

pub fn into_value(self) -> Vec<u8>

Consumes Self and returns the inner raw value.

Trait Implementations

impl AsRef<[u8]> for RawValue<Vec<u8>>

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

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

impl<V> Clone for RawValue<V>

where V: Clone + Value,

fn clone(&self) -> RawValue<V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V> Compress for RawValue<V>

where V: Value,

type Compressed = Vec<u8>

Compressed type.

fn uncompressable_ref(&self) -> Option<&[u8]>

If the type cannot be compressed, return its inner reference as Some(self.as_ref())

fn compress(self) -> <RawValue<V> as Compress>::Compressed

Compresses data going into the database.

fn compress_to_buf<B>(&self, buf: &mut B)

where B: BufMut + AsMut<[u8]>,

Compresses data to a given buffer.

impl<V> Debug for RawValue<V>

where V: Debug + Value,

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

Formats the value using the given formatter.

impl<V> Decompress for RawValue<V>

where V: Value,

fn decompress(value: &[u8]) -> Result<RawValue<V>, DatabaseError>

Decompresses data coming from the database.

fn decompress_owned(value: Vec<u8>) -> Result<RawValue<V>, DatabaseError>

Decompresses owned data coming from the database.

impl<V> From<V> for RawValue<V>

where V: Value,

fn from(value: V) -> RawValue<V>

Converts to this type from the input type.

impl<V> Hash for RawValue<V>

where V: Hash + Value,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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<V> Ord for RawValue<V>

where V: Ord + Value,

fn cmp(&self, other: &RawValue<V>) -> 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<V> PartialEq for RawValue<V>

where V: PartialEq + Value,

fn eq(&self, other: &RawValue<V>) -> 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<V> PartialOrd for RawValue<V>

where V: PartialOrd + Value,

fn partial_cmp(&self, other: &RawValue<V>) -> 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<V> Serialize for RawValue<V>

where V: Value,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<V> Eq for RawValue<V>

where V: Eq + Value,

impl<V> StructuralPartialEq for RawValue<V>

where V: Value,

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
