Enum bt_bencode::Value

pub enum Value {
    ByteStr(ByteBuf),
    Int(Number),
    List(Vec<Value>),
    Dict(BTreeMap<ByteBuf, Value>),
}

Represents a valid Bencode value.

It is useful when it is unknown what the data may contain (e.g. when different kinds of messages can be received in a network packet).

Variants

ByteStr(ByteBuf)

A byte string.

Encoded strings can contain non-UTF-8 bytes, so a byte string is used to represent “strings”.

Int(Number)

An integer which can be signed or unsigned.

List(Vec<Value>)

A list of values.

Dict(BTreeMap<ByteBuf, Value>)

A dictionary of values.
