}A generic trait for converting a value to a number.
Required Methods
fn to_i64(&self) -> Option<i64>
Converts the value of self to an i64.
fn to_u64(&self) -> Option<u64>
Converts the value of self to an u64.
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.
