Enum i_slint_compiler::expression_tree::BuiltinMacroFunction

pub enum BuiltinMacroFunction {
    Min,
    Max,
    Mod,
    CubicBezier,
    Rgb,
    Debug,
}

A builtin function which is handled by the compiler pass

Builtin function expect their arguments in one and a specific type, so that’s easier for the generator. Macro however can do some transformation on their argument.

Variants

Min

Transform min(a, b, c, ..., z) into a series of conditional expression and comparisons

Max

Transform max(a, b, c, ..., z) into a series of conditional expression and comparisons

Mod

Add the right conversion operations so that the return type is the same as the argument type

CubicBezier

Rgb

The argument can be r,g,b,a or r,g,b and they can be percentages or integer. transform the argument so it is always rgb(r, g, b, a) with r, g, b between 0 and 255.

Debug

transform debug(a, b, c) into debug a + " " + b + " " + c
