Struct StructType 

#[non_exhaustive]
pub struct StructType {
    pub fields: Vec<Field>,
    /* private fields */
}

StructType defines the fields of a STRUCT type.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fields: Vec<Field>

The list of fields that make up this struct. Order is significant, because values of this struct type are represented as lists, where the order of field values matches the order of fields in the StructType. In turn, the order of fields matches the order of columns in a read request, or the order of fields in the SELECT clause of a query.

Implementations

impl StructType

pub fn new() -> Self

Creates a new default instance.

pub fn set_fields<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Field>,

Sets the value of fields.

Trait Implementations

impl Clone for StructType

fn clone(&self) -> StructType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructType

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

Formats the value using the given formatter.

impl Default for StructType

fn default() -> StructType

Returns the “default value” for a type.

impl Message for StructType

fn typename() -> &'static str

The typename of this message.

impl PartialEq for StructType

fn eq(&self, other: &StructType) -> 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.
