Enum JsonFieldEncoding 

pub enum JsonFieldEncoding {
    Utf8,
    Utf8Json,
    DecimalStr,
    UInt64,
    Float64,
    Boolean,
}

Variants

Utf8

Utf8Json

DecimalStr

Exact decimal written as Utf8, read back from Utf8, Utf8View, or Float64.

The Float64 case is what lets catalog files written before a field moved from f64 to Decimal keep decoding: Decimal’s Deserialize accepts both a JSON string and a JSON number, so no version discriminator is needed.

UInt64

Float64

Boolean
