Enum bt_bencode::Value

source · 
pub enum Value {
    ByteStr(ByteString),
    Int(Number),
    List(Vec<Value>),
    Dict(BTreeMap<ByteString, Value>),
}
Expand description

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(ByteString)

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<ByteString, Value>)

A dictionary of values.
