Struct TextEncodeSettings 

Source 
pub struct TextEncodeSettings {
    pub extra_float_digits: i32,
}
Expand description

Session settings that affect how values are encoded as text.

PostgreSQL’s text output for some types depends on session state. Encoders whose output must not depend on the session, such as everything evaluated in the dataflow layer, use TextEncodeSettings::STABLE.

Fields§

§extra_float_digits: i32

PostgreSQL’s extra_float_digits: positive values select the shortest round-trippable encoding for float4 and float8, while zero and negative values limit output to FLOAT4_DIGITS or FLOAT8_DIGITS plus this value significant digits.

Implementations§

Source§
