Functions

empty?(value)

Returns true if the value would be considered empty.

value type	result
`nil`	`true`
binary	`String.trim_leading(value) == ""`
list	`value == []`
tuple	`tuple_size(value) == 0`
map	`map_size(value) == 0`
Enumerable	`Enum.empty?(value)`
anything else	`false`

nil is empty
non-struct maps are empty if map_size/1 is 0
lists are empty if they equal []
strings are empty if, when trimmed of leading spaces, they are equal to an empty string ("")
values implementing the Enumerable protocol are empty if Enum.empty?/1 returns true
all other values are not empty
