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` } }
