Enum Value 

pub enum Value {
    Null,
    Integer(i64),
    Float(f64),
    Text(String),
    BlobBase64(String),
}

Logical value type used for SQL parameters and decoded rows.

Variants

Null

SQL null.

Integer(i64)

Signed integer.

Float(f64)

Floating-point number (must be finite).

Text(String)

UTF-8 text.

BlobBase64(String)

Base64-encoded binary payload.

Implementations

impl Value

pub fn null() -> Self

Creates a null value.

pub fn integer(value: i64) -> Self

Creates an integer value.

pub fn float(value: f64) -> Self

Creates a float value.

pub fn text(value: impl Into<String>) -> Self

Creates a text value.

pub fn blob_base64(value: impl Into<String>) -> Self

Creates a base64 blob value.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

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(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(value: i64) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 Value

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
