impl<E> UnaryFunc<E>

Source

pub fn variant_name(&self) -> &'static str

The canonical name of this variant, as declared by its FuncName impl.

Source

pub fn try_map_expr<'a, E2: TryFrom<&'a E>>( &'a self, ) -> Result<UnaryFunc<E2>, E2::Error>

Rebuilds this function with any stored expressions converted to E2. Fails if any expression conversion fails, reporting the first failure.

Source

pub fn map_expr<'a, E2: From<&'a E>>(&'a self) -> UnaryFunc<E2>

Rebuilds this function with any stored expressions converted to E2.

Source §

Attempts to construct a UnaryFunc from the canonical name of one of its variants, as declared by the variant’s FuncName impl (the name of the underlying Rust function, e.g. cast_int32_to_numeric).

Intended for test tooling that needs to name exact function variants. Only variants whose inner function deserializes from no data (unit functions and functions all of whose parameters may default to None) are constructible. Returns None for other variants and for unknown names. Returns the MIR instantiation.

Source

pub fn variant_names() -> impl Iterator<Item = &'static str>

The canonical names of all variants, in declaration order.

Source §

impl<E> UnaryFunc<E>

Source

pub fn is(&self) -> Option<&'static str>

If the unary_func represents “IS X”, return X.

A helper method for being able to print Not(IsX) as IS NOT X.
