Enum ParamValue 

pub enum ParamValue {
    Null,
    Bool(bool),
    Int64(i64),
    UInt64(u64),
    Float64(f64),
    DecimalText(String),
    Text(String),
    Bytes(Vec<u8>),
    Vector(Vec<f32>),
    Json(Vec<u8>),
    Timestamp(i64),
    Uuid([u8; 16]),
}

Transport-neutral parameter value vocabulary from ADR 0015.

UInt64 and DecimalText extend the ADR’s ten-variant enumeration with the lossless wire/body number vocabulary. The legacy binary protocol binds unsigned parameters over the full u64 range, while JSON transports carry beyond-native precision in $decimal envelopes; the seam preserves both instead of narrowing them before execution.

Implementations

impl ParamValue

pub fn decode_json(value: &Value) -> Result<Self, String>

Decode the shared JSON parameter vocabulary used by HTTP, MCP, and stdio JSON-RPC. Typed single-key envelopes preserve values ordinary JSON cannot represent losslessly.

pub fn decode_json_lossy(value: &Value) -> Self

Decode a general JSON payload while preserving unrecognized typed envelopes as JSON. Row insertion historically accepts those objects as document values rather than rejecting the request as a bind error.

Trait Implementations

impl Clone for ParamValue

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamValue

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

Formats the value using the given formatter.

impl From<ParamValue> for Value

fn from(value: ParamValue) -> Self

Converts to this type from the input type.

impl PartialEq for ParamValue

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
