Struct RawValue 

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

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 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,

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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to #147781)

Restrict a value to a certain range.

impl<V> PartialEq for RawValue<V>

where V: PartialEq + Value,

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

impl<V> StructuralPartialEq for RawValue<V>

where V: PartialEq + Value,

Layout

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.
