Trait ExecSpecSeqIndexOf 

pub trait ExecSpecSeqIndexOf<'a>: Sized + DeepView {
    type Elem: DeepView;

    // Required method
    exec fn exec_index_of(self, needle: Self::Elem) -> usize;
}

Spec for executable version of Seq::index_of.

Required Associated Types

type Elem: DeepView

Required Methods

exec fn exec_index_of(self, needle: Self::Elem) -> usize

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl<'a, T: DeepView + PartialEq> ExecSpecSeqIndexOf<'a> for &'a [T]

where &'a T: ExecSpecEq<'a, Other = &'a T>,

exec fn exec_index_of(self, needle: Self::Elem) -> res : usize

ensures

res == self.deep_view().index_of(needle.deep_view()),

type Elem = T
