Struct JsonSetOptions 

pub struct JsonSetOptions<'a> { /* private fields */ }

Options for the json_set command

Implementations

impl<'a> JsonSetOptions<'a>

pub fn condition(self, condition: SetCondition<'a>) -> Self

Sets the value only if the condition holds.

JSON.SET accepts only NX and XX; the value-comparison variants are rejected by the server.

pub fn fpha(self, fp_type: JsonFpType) -> Self

Forces floating-point homogeneous arrays to use the given type.

JSON stores numbers as text, so the server cannot infer the type an array of floats was produced with. Declaring it trades precision for memory: FP64 and FP32 keep more of it, BF16 and FP16 halve the footprint of FP32. A value that does not fit the declared type makes the command fail with a value out of range error.

Trait Implementations

impl<'a> Default for JsonSetOptions<'a>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<SetCondition<'a>> for JsonSetOptions<'a>

fn from(condition: SetCondition<'a>) -> Self

Converts to this type from the input type.

impl<'a> Serialize for JsonSetOptions<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
