Enum DefaultValue 

pub enum DefaultValue {
    Bool(bool),
    Integer(i64),
    Float(f64),
    String(String),
}

A value that can be a string, boolean, or number. This is used for default values where columns can use literal values directly.

Variants

Bool(bool)

Integer(i64)

Float(f64)

String(String)

Implementations

impl DefaultValue

pub fn to_sql(&self) -> String

Convert to SQL string representation Empty strings are converted to ‘’ (SQL empty string literal)

pub fn is_string(&self) -> bool

Check if this is a string type (needs quoting for certain column types)

pub fn is_empty_string(&self) -> bool

Check if this is an empty string

Trait Implementations

impl Clone for DefaultValue

fn clone(&self) -> DefaultValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DefaultValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for DefaultValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for DefaultValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for DefaultValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for DefaultValue

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i32> for DefaultValue

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for DefaultValue

fn from(n: i64) -> Self

Converts to this type from the input type.

impl JsonSchema for DefaultValue

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for DefaultValue

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DefaultValue

impl StructuralPartialEq for DefaultValue
