45```rust
46fn foo() -> Result<u8, ()> {

55This diagnostic is triggered if pattern lacks some fields that exist in the corresponding structure.
56
57Example:
58
59```rust

74
75Example:
76
77```rust
78struct A { a: u8, b: u8 }
79
80let a = A { a: 10 };

90=== no-such-field
91**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/hir_ty/src/diagnostics.rs#L39[diagnostics.rs]

114=== unresolved-proc-macro
115**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/hir_def/src/diagnostics.rs#L131[diagnostics.rs]
116
117This diagnostic is shown when a procedural macro can not be found. This usually means that
118procedural macro support is simply disabled (and hence is only a weak hint instead of an error),
119but can also indicate project setup problems.
