Struct Value 

pub struct Value {
    pub sum: Option<Sum>,
}

Encodes values that the ledger accepts as command arguments and emits as contract arguments.

The values encoding use different classes of non-empty strings as identifiers. Those classes are defined as follows:

• NameStrings are strings with length <= 1000 that match the regexp [A-Za-z\$_][A-Za-z0-9\$_]*.
• PackageIdStrings are strings with length <= 64 that match the regexp \[A-Za-z0-9\-_ \]+.
• PartyIdStrings are strings with length <= 255 that match the regexp \[A-Za-z0-9:\-_ \]+.
• ParticipantIdStrings are strings with length <= 255 that match the regexp \[A-Za-z0-9:\-_ \]+.
• LedgerStrings are strings with length <= 255 that match the regexp \[A-Za-z0-9#:\-_/ \]+.
• UserIdStrings are strings with length <= 128 that match the regexp \[a-zA-Z0-9@^$.!`\-#+'~_|:\]+.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl Message for Value

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,
