Enum WriteValue 

pub enum WriteValue {
    Literal(Value),
    GeneratedId(usize),
    GeneratedText {
        index: usize,
        prefix: String,
    },
    GeneratedJson {
        index: usize,
        marker: String,
        template: Value,
    },
}

A write value can refer to an earlier inserted or ensured record.

Implementations

impl WriteValue

pub fn generated_index(&self) -> Option<usize>

Identifies the prior transaction result used by a typed generated value.

pub fn relocate(&mut self, offset: usize) -> Result<(), DatabaseError>

Relocates references when a transaction-local plan is appended.

Trait Implementations

impl Clone for WriteValue

fn clone(&self) -> WriteValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WriteValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WriteValue

fn eq(&self, other: &WriteValue) -> 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 Serialize for WriteValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
