Enum rshark::Val

pub enum Val {
    Signed(i64),
    Unsigned {
        value: u64,
        radix: u8,
    },
    Enum(u64, &'static str),
    String(String),
    Address {
        bytes: Vec<u8>,
        encoded: String,
    },
    Subpacket(Vec<NamedValue>),
    Bytes(Vec<u8>),
    Error(Error),
    Warning(Error),
}

A value parsed from a packet.

TODO

This value type isn't as expressive as would be required for a real Wireshark replacement just yet. Additional needs include:

• tracking original bytes (by reference or by index?)

Variants

Signed	A signed integer, in machine-native representation.
Unsigned	An unsigned integer, in machine-native representation, and a radix (base) for when we display the value to the user (e.g., 0x100 vs 256). Fields value radix
Enum	An integer value that represents a symbolic value.
String	A UTF-8–encoded string.
Address	A network address, which can have its own special encoding. Fields bytes encoded
Subpacket	A set of named values from an encapsulated packet (e.g., TCP within IP).
Bytes	Raw bytes, e.g., a checksum or just unparsed data.
Error	An error that stopped further parsing.
Warning	A problem with a packet that did not stop further parsing (e.g., bad checksum).
