Struct ScalarTextCodec 

pub struct ScalarTextCodec {
    pub name: &'static str,
    pub field: &'static str,
    pub value_type: ValueType,
    pub trim: bool,
}

Configurable text representation for a scalar field. Parsing and result conversion use the same logical type, so cursor and database binds remain typed while the public text format is centralized in one codec.

Fields

name: &'static str

field: &'static str

value_type: ValueType

trim: bool

Trait Implementations

impl Clone for ScalarTextCodec

fn clone(&self) -> ScalarTextCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for ScalarTextCodec

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

Convert one decoded result value into its public representation.

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 fingerprint(&self) -> u64

Stable identity including codec configuration.

impl Copy for ScalarTextCodec

impl Debug for ScalarTextCodec

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

Formats the value using the given formatter.
