    // Required methods
    fn is_not_empty(self, err: E) -> Result<Vec<T>, E>;
    fn count<U, F: Fn(usize, Vec<T>) -> Result<U, E>>(

}

A trait providing extensions for vectors and results containing vectors, offering additional utility methods.

Required Methods

fn is_not_empty(self, err: E) -> Result<Vec<T>, E>

Checks if the vector is not empty.

Parameters

• err: The error to return if the vector is empty.

Returns

• Result<Vec<T>, E>: Ok with the original vector if not empty; otherwise, Err with the provided error.

fn count<U, F: Fn(usize, Vec<T>) -> Result<U, E>>(self, op: F) -> Result<U, E>

Applies a function to the vector, providing the length and the vector itself.

Parameters

• op: A closure that takes the length of the vector and the vector, returning a Result.

Returns

• Result<U, E>: The result of the closure applied to the length and the vector.

fn into_count(self) -> Result<usize, E>

Converts the vector into its count.

Returns

• Result<usize, E>: Ok with the count of elements if the Result is Ok; otherwise, the original Err.

fn into_result(self) -> Result<Vec<T>, E>

Converts the vector into a Result type.

Returns

• Result<Vec<T>, E>: Ok with the original vector.

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.
