Show 18 variants Nothing, Boolean(bool), Int8(i8), Int16(i16), Int32(i32), Int64(i64), Int128(i128), Int256([u8; 32]), Uint8(u8), Uint16(u16), Uint32(u32), Uint64(u64), Double(f64), Bytes(Vec<u8>), Yson(Vec<u8>), Variant { tag: u16, value: Box<Value>, }, RepeatedVariants(Vec<Variant>), Tuple(Vec<Value>),

Expand description

A dynamically decoded Skiff value.

Every variant maps directly to one WireType. Compound values retain tags and wire order so they can be re-encoded without a lossy conversion.

Variants§

§

Nothing

nothing, an empty payload.

§

Boolean(bool)

boolean.

§

Int8(i8)

int8.

§

Int16(i16)

int16.

§

Int32(i32)

int32.

§

Int64(i64)

int64.

§

Int128(i128)

int128.

§

Int256([u8; 32])

int256, kept as its little-endian two’s-complement bytes.

§

Uint8(u8)

uint8.

§

Uint16(u16)

uint16.

§

Uint32(u32)

uint32.

§

Uint64(u64)

uint64.

§

Double(f64)

double.

§

Bytes(Vec<u8>)

string32, which may contain non-UTF-8 bytes.

§

Yson(Vec<u8>)

yson32, kept as one binary-YSON payload.

§

Variant

A variant8 or variant16 child selected by tag.

Fields

§tag: u16

The selected child index.

§value: Box<Value>

The selected child’s value.

§

RepeatedVariants(Vec<Variant>)

A repeated_variant8 or repeated_variant16 sequence.

§

Tuple(Vec<Value>)

A tuple, in schema-child order.
