eq :: Eq value => Field row value -> value -> Expr row
```

Signature types: [`Eq`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Data-Eq.html#t:Eq), [`Field`](/en/haskell/latest/reference/libtmux-query-t-field/), [`Expr`](/en/haskell/latest/reference/libtmux-query-t-expr/).

Exact equality in the field's declared type. No Unicode normalization,
 case folding or byte-to-text conversion is implicit.
