dump
dump(x)
Show all user-visible structure of a value.
Examples
julia> struct Point
x::Int
y::Int
end
julia> p = Point(3, 4)
Point(3, 4)
julia> dump(p)
Point
x: Int64 3
y: Int64 4In the above example, we define a Point struct with x and y fields. Then, we create an instance p of the Point struct with values (3, 4). The dump function is used to display the internal structure of the object p.
Common mistake example:
julia> dump(5)
ERROR: ArgumentError: `dump` requires a mutable struct or mutable struct instance as an argumentIn this example, the dump function is used on an immutable value (integer 5). The dump function expects a mutable struct or instance, so it cannot be used on immutable values.
Note: The dump function is commonly used for debugging and introspection purposes to inspect the internal structure of objects. It is particularly useful when working with complex data structures or user-defined types.
