InlineLevel

struct InlineLevel

Names the levels the @inline decorator accepts.

@inline takes one of these, so a misspelling is caught where it is written, and a comptime expression can choose a level per instantiation:

@inline(.always)
def doubled(x: Int) -> Int:
return x * 2

@inline(policy)
def scaled[policy: InlineLevel](x: Int) -> Int:
return x * 3

def main():
print(doubled(1) + scaled[.never](2))

Implemented traits

AnyType, Copyable, Deinitable, Equatable, ImplicitlyCopyable, Movable, RegisterPassable, TrivialRegisterPassable

comptime members

always

comptime always = InlineLevel(value=Int(1))

Always inlines the function.

automatic

comptime automatic = InlineLevel(value=Int(0))

Leaves the decision to the compiler's heuristics.

never

comptime never = InlineLevel(value=Int(4))

Never inlines the function.

nodebug

comptime nodebug = InlineLevel(value=Int(2))

Always inlines the function, and drops its debug info when inlining.

Methods

__eq__

def __eq__(self, rhs: Self) -> Bool

Compare two levels.

Args:

  • rhs (Self): The level to compare against.

Returns:

Bool: True if the levels are the same.
