inline functions
Learn inline functions in Zig with a construct-specific explanation, unique example, engineering boundary, and mastery check.
inline functions is a focused Zig topic inside Functions. This lesson explains the construct itself, the state or value it operates on, and the observable result it produces.
Read the example as a small executable experiment. Identify the exact syntax that belongs to inline functions, then change one input and predict the result before running it.
Topic-specific example
inline fn double(x:i32)i32{return x*2;}
inline functions has rules that are easy to miss when the example is copied mechanically. Check the feature-specific boundary shown by this construct: scope, mutability, evaluation order, type constraints, lifetime, error behavior, compile-time restrictions, or resource cleanup where applicable.
