Error code E0026

A struct pattern attempted to extract a nonexistent field from a struct.

Erroneous code example:

#![allow(unused)] fn main() { struct Thing { x: u32, y: u32, } let thing = Thing { x: 0, y: 0 }; match thing { Thing { x, z } => {} // error: `Thing::z` field doesn't exist } }

If you are using shorthand field patterns but want to refer to the struct field by a different name, you should rename it explicitly. Struct fields are identified by the name used before the colon : so struct patterns should resemble the declaration of the struct type being matched.

#![allow(unused)] fn main() { struct Thing { x: u32, y: u32, } let thing = Thing { x: 0, y: 0 }; match thing { Thing { x, y: z } => {} // we renamed `y` to `z` } }
