}

Vec<Option<Self>>: TryFromSexp with an error that converts into SexpError, with Self as the bound’s self type.

Plumbing for the Vec<Option<T>> blanket below: see the module docs (#1682).

Required Associated Constants

const VEC_OPTION_NATIVE_BORROW: Option<NativeBorrow>

<Vec<Option<Self>> as TryFromSexp>::NATIVE_BORROW.

const VEC_OPTION_CHARACTER_ONLY: bool

<Vec<Option<Self>> as TryFromSexp>::CHARACTER_ONLY.

Required Methods

fn vec_option_try_from_sexp( sexp: SEXP, check: &ElementCheck<'_>, ) -> Result<Vec<Option<Self>>, SexpError>

<Vec<Option<Self>> as TryFromSexp>::__mx_try_from_sexp_with_check: the vector, with check run where Vec<Option<Self>> keeps an element’s class.

unsafe fn vec_option_try_from_sexp_unchecked( sexp: SEXP, check: &ElementCheck<'_>, ) -> Result<Vec<Option<Self>>, SexpError>

<Vec<Option<Self>> as TryFromSexp>::__mx_try_from_sexp_unchecked_with_check.

Safety

As TryFromSexp::try_from_sexp_unchecked.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors
