Trait SubsliceExt 

pub trait SubsliceExt: Sealed {
    // Required methods
    fn find(&self, other: &Self) -> Option<usize>;
    fn rfind(&self, other: &Self) -> Option<usize>;
}

Trait of types which can be searched for subsequences

Required Methods

fn find(&self, other: &Self) -> Option<usize>

Find the first subslice of self which is equal to other, and return the index of its start.

O(self.len() + other.len()) time

fn rfind(&self, other: &Self) -> Option<usize>

Find the last subslice of self which is equal to other, and return the index of its start.

O(self.len() + other.len()) time

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
