Struct ListResultCodec 

pub struct ListResultCodec { /* private fields */ }

Literal separated database text -> typed presentation list. This does not add PostgreSQL array-column operators or change the database bind type.

Implementations

impl ListResultCodec

pub fn new( name: &'static str, field: &'static str, separator: &'static str, item_type: ValueType, max_items: usize, ) -> Result<ListResultCodec, ConfigError>

Trait Implementations

impl Clone for ListResultCodec

fn clone(&self) -> ListResultCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for ListResultCodec

fn name(&self) -> &'static str

Stable name used in schema and policy fingerprints.

fn supports(&self, field: &FieldMeta) -> bool

Whether this codec handles the field.

fn parse(&self, _: &FieldMeta, input: &str) -> Result<ScalarValue, String>

Convert one external value into the field’s validated query value.

fn format_input( &self, _: &FieldMeta, value: &ScalarValue, ) -> Result<String, String>

Canonical RPC representation. Encoders verify that parsing this text recovers the original database value; lossy codecs must override it.

fn format_result( &self, _: &FieldMeta, value: RowValue, ) -> Result<RowValue, String>

Convert one decoded result value into its public representation.

fn fingerprint(&self) -> u64

Stable identity including codec configuration.

impl Debug for ListResultCodec

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

Formats the value using the given formatter.
