Enum rql::repr::Representation

pub enum Representation {
    BinaryStable,
    BinaryDynamic,
    HumanReadable,
}

Types of data representations

Variants

BinaryStable

A binary format that is not tolerant to schema changes

Use this only if you are absolutely certain that your schema will not change.

Uses bincode

BinaryDynamic

A binary format that is tolerant to certain schema changes

Columns and tables can be added, but not reordered or removed. Use serde attributes to enable backward compatibility.

Uses MessagePack

HumanReadable

A human readable format that is tolerant to most schema changes.

Columns and tables can be added, reordered, or removed. Use serde attributes to enable backward compatibility.

Uses YAML

Methods

impl Representation

pub fn serialize<S>(self, data: &S) -> Result<Vec<u8>, String> where
    S: Serialize, 

Use this Representation to serialize some data

pub fn deserialize<B, D>(self, bytes: B) -> Result<D, String> where
    B: AsRef<[u8]>,
    D: DeserializeOwned, 

Use thie Representation to deserialize some data

Trait Implementations

impl Clone for Representation

fn clone(&self) -> Representation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Representation

fn cmp(&self, other: &Representation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialOrd<Representation> for Representation

fn partial_cmp(&self, other: &Representation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] 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 PartialEq<Representation> for Representation

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

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Copy for Representation

impl Eq for Representation

impl Debug for Representation

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

Formats the value using the given formatter.

impl Serialize for Representation

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

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Representation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
