Enum Value 

pub enum Value {
    Null,
    Integer(i64),
    Real(f64),
    Text(String),
    Blob(Vec<u8>),
}

The five SQLite storage classes — this crate’s currency for both statement parameters and result-row values.

Variants

Null

SQL NULL.

Integer(i64)

A signed 64-bit integer.

Real(f64)

A 64-bit IEEE-754 float.

Text(String)

A UTF-8 string.

Blob(Vec<u8>)

An arbitrary byte string.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Self

Returns a duplicate 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 From<&str> for Value

fn from(v: &str) -> Self

Converts to this type from the input type.

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

fn from(v: Option<T>) -> Self

None → Value::Null; Some(v) → v’s own conversion.

impl From<String> for Value

fn from(v: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Value

fn from(v: Vec<u8>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(v: bool) -> Self

false → 0, true → 1 — SQLite has no native boolean storage class.

impl From<f64> for Value

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(v: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(v: i64) -> Self

Converts to this type from the input type.

impl PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Value
