Struct StructField

pub struct StructField {
    pub id: i32,
    pub name: String,
    pub required: bool,
    pub field_type: Type,
    pub doc: Option<String>,
}

A struct is a tuple of typed values. Each field in the tuple is named and has an integer id that is unique in the table schema. Each field can be either optional or required, meaning that values can (or cannot) be null. Fields may be any type. Fields may have an optional comment or doc string. Fields can have default values.

Fields

id: i32

Id unique in table schema

name: String

Field Name

required: bool

Optional or required

field_type: Type

Datatype

doc: Option<String>

Fields may have an optional comment or doc string.

Implementations

impl StructField

pub fn new( id: i32, name: &str, required: bool, field_type: Type, doc: Option<String>, ) -> Self

Creates a new StructField with the given parameters

Arguments

• id - Unique identifier for this field within the table schema
• name - Name of the field
• required - Whether this field is required (true) or optional (false)
• field_type - The data type of this field
• doc - Optional documentation string for this field

Trait Implementations

impl Clone for StructField

fn clone(&self) -> StructField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StructField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StructField

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
