This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

setRangeValue

Public Function
std.bit_set.Integer.setRangeValue
pub fn setRangeValue(self: *Self, range: Range, value: bool) void

Changes the value of all bits in the specified range to match the passed boolean.
