Struct Type 

pub struct Type(/* private fields */);

Spanner type definition.

Implementations

impl Type

pub fn code(&self) -> TypeCode

Returns the type code.

pub fn array_element_type(&self) -> Option<Type>

Returns the element type of the array, or None if this type is not an array.

pub fn struct_type(&self) -> Option<&StructType>

Returns the struct type metadata, or None if this type is not a struct.

When code() == TypeCode::Struct, this provides the field names and their types. This is essential for reconstructing named fields from the positional ListValue wire format that Spanner uses for STRUCT values.
