Provided methods

fn to_isize(&self) -> Option<isize>

Converts the value of self to an isize.

fn to_i8(&self) -> Option<i8>

Converts the value of self to an i8.

fn to_i16(&self) -> Option<i16>

Converts the value of self to an i16.

fn to_i32(&self) -> Option<i32>

Converts the value of self to an i32.

fn to_i128(&self) -> Option<i128>

Converts the value of self to an i128.

This method is only available with feature i128 enabled on Rust >= 1.26.

The default implementation converts through to_i64(). Types implementing this trait should override this method if they can represent a greater range.

fn to_usize(&self) -> Option<usize>

Converts the value of self to a usize.

fn to_u8(&self) -> Option<u8>

Converts the value of self to an u8.

fn to_u16(&self) -> Option<u16>

Converts the value of self to an u16.

fn to_u32(&self) -> Option<u32>

Converts the value of self to an u32.

fn to_u128(&self) -> Option<u128>

Converts the value of self to an u128.

This method is only available with feature i128 enabled on Rust >= 1.26.

The default implementation converts through to_u64(). Types implementing this trait should override this method if they can represent a greater range.

fn to_f32(&self) -> Option<f32>

Converts the value of self to an f32.

fn to_f64(&self) -> Option<f64>

Converts the value of self to an f64.
