Struct snarkvm_console_program::Identifier

pub struct Identifier<N: Network>(_, _);

An identifier is an immutable UTF-8 string, represented as a constant field element in the CurrentNetwork.

Requirements

The identifier must not be an empty string. The identifier must not start with a number. The identifier must be alphanumeric, and may include underscores. The identifier must not consist solely of underscores. The identifier must fit within the data capacity of a base field element.
