Expand description

A generic trait for converting a value to a number.

Required methods

`fn to_i64(&self) -> Option<i64>`[src]

Converts the value of self to an i64.

`fn to_u64(&self) -> Option<u64>`[src]

Converts the value of self to an u64.

Provided methods

`fn to_isize(&self) -> Option<isize>`[src]

Converts the value of self to an isize.

`fn to_i8(&self) -> Option<i8>`[src]

Converts the value of self to an i8.

`fn to_i16(&self) -> Option<i16>`[src]

Converts the value of self to an i16.

`fn to_i32(&self) -> Option<i32>`[src]

Converts the value of self to an i32.

`fn to_i128(&self) -> Option<i128>`[src]

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>`[src]

Converts the value of self to a usize.

`fn to_u8(&self) -> Option<u8>`[src]

Converts the value of self to an u8.

`fn to_u16(&self) -> Option<u16>`[src]

Converts the value of self to an u16.

`fn to_u32(&self) -> Option<u32>`[src]

Converts the value of self to an u32.

`fn to_u128(&self) -> Option<u128>`[src]

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>`[src]

Converts the value of self to an f32.

`fn to_f64(&self) -> Option<f64>`[src]

Converts the value of self to an f64.
