Enum StrOrBoolOrArray 

#[non_exhaustive]
pub enum StrOrBoolOrArray {
    Str(String),
    Array(Vec<String>),
    Bool(bool),
}

A JSON value that can be a string, an array of strings, or a boolean.

Used for inline "unique" and "index" declarations on a ColumnDef:

• true / false — enable or disable the constraint with an auto-generated name.
• A single string — the constraint name (used to group columns into a composite constraint).
• An array of strings — a list of constraint names for multi-group membership.

This enum is #[non_exhaustive]: new variants may be added in future releases. Downstream match expressions should include a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Str(String)

A named constraint or group identifier.

Array(Vec<String>)

Multiple constraint group names for multi-group membership.

Bool(bool)

true to enable with an auto-generated name; false to disable.

Implementations

impl StrOrBoolOrArray

pub fn as_str(&self) -> Option<&str>

Returns the string value when this is Str.

Trait Implementations

impl Clone for StrOrBoolOrArray

fn clone(&self) -> StrOrBoolOrArray

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrOrBoolOrArray

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StrOrBoolOrArray

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for StrOrBoolOrArray

impl JsonSchema for StrOrBoolOrArray

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 StrOrBoolOrArray

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
