len
len :: proc(v: Type) -> int
The len
built-in procedure return the length of v
, according to its type:
Array: the number of elements in v Pointer to array: the number of elements in v^ (even if v is nil) Slice: the number of elements in v; if v in nil, len(v) is zero Dynamic array: the number of elements in v; if v in nil, len(v) is zero Map: the number of elements in v; if v in nil, len(v) is zero String: the number of bytes in v
If the parameter passed is an enumeration type, it will return the number of enumeration values:
Foo :: enum {A, B, C}; #assert(len(Foo) == 3);
cap
cap :: proc(v: Type) -> int
The cap
built-in procedure return the capacity of v
, according to its type:
Dynamic array: the maximum length the dynamic array can reach before it requires a resize; if v in nil, len(v) is zero
