Struct TableMapper

pub struct TableMapper { /* private fields */ }

Default implementation of the FieldMapper trait

Provides bidirectional mapping between field IDs and names using HashMaps for efficient lookups.

Implementations

impl TableMapper

pub fn new() -> Self

Creates a new empty TableMapper

pub fn deserialize_row<T>( &self, row: HashMap<String, Value>, ) -> Result<T, Error>

where T: DeserializeOwned,

Deserializes a row into a user-defined type

Type Parameters

• T - The type to deserialize into. Must implement DeserializeOwned.

Arguments

• row - The row data as a HashMap

Returns

• Result<T, serde_json::Error> - The deserialized struct or an error

pub fn convert_to_field_names( &self, row: HashMap<String, Value>, ) -> HashMap<String, Value>

Converts field IDs to field names in a row

Arguments

• row - The row data with field IDs as keys

Returns

• HashMap with field names as keys

pub fn convert_to_field_ids( &self, row: HashMap<String, Value>, ) -> HashMap<String, Value>

Converts field names to field IDs in a row

Arguments

• row - The row data with field names as keys

Returns

• HashMap with field IDs as keys

Trait Implementations

impl Clone for TableMapper

fn clone(&self) -> TableMapper

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for TableMapper

fn default() -> TableMapper

Returns the “default value” for a type.

impl FieldMapper for TableMapper

fn map_fields(&mut self, fields: Vec<TableField>)

fn get_field_id(&self, name: &str) -> Option<u64>

Gets the field ID corresponding to a field name

fn get_field_name(&self, id: u64) -> Option<String>

Gets the field name corresponding to a field ID

fn get_fields(&self) -> Vec<TableField>

Gets all mapped fields
