A mutation field for a table.

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.

name: String

Field name (e.g., “insertUsers”)

table_name: String

Table name

schema_name: String

Schema the table lives in

mutation_type: MutationType

Mutation type

pk_columns: Vec<(String, String)>

Primary key columns, as (column name, PostgreSQL type).

Populated for by-PK mutations so the resolver can target the row by its key. Empty for bulk mutations.

return_type: String

GraphQL return type

type_name: String

GraphQL row object type name.

local_type_name: String

Base name for helper types owned by this table.

description: Option<String>
