Struct JsonNamedParamsBuilder 

pub struct JsonNamedParamsBuilder { /* private fields */ }

Builder for named JSON parameters.

Example

use hyperdb_api_core::client::grpc::QueryParameters;

let params = QueryParameters::json_named()
    .add("user_id", &123)?
    .add("email", &"user@example.com")?
    .build();

Implementations

impl JsonNamedParamsBuilder

pub fn new() -> Self

Creates a new builder.

pub fn add<T: Serialize>( self, name: impl Into<String>, value: &T, ) -> Result<Self, Error>

Adds a named parameter.

Arguments

• name - Parameter name (without the colon prefix)
• value - Parameter value (must be JSON-serializable)

Errors

Returns a serde_json::Error if value cannot be serialized to JSON.

pub fn add_null(self, name: impl Into<String>) -> Self

Adds a null parameter.

pub fn build(self) -> QueryParameters

Builds the QueryParameters.

Panics

Does not panic in practice. The serde_json::to_string call on a Map<String, Value> is infallible for valid JSON trees — serde_json only fails when a user-defined Serialize impl returns an error, which cannot happen for the already-validated Value payloads inserted via Self::add and Self::add_null.

Trait Implementations

impl Debug for JsonNamedParamsBuilder

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

Formats the value using the given formatter.

impl Default for JsonNamedParamsBuilder

fn default() -> JsonNamedParamsBuilder

Returns the “default value” for a type.
