function pointers

Learn function pointers in Zig with a construct-specific explanation, unique example, engineering boundary, and mastery check.

10 min read • Intermediate

function pointers 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 function pointers, then change one input and predict the result before running it.

Topic-specific example

const Op = *const fn(i32,i32)i32;
Edge case / engineering note

function pointers 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.
