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. If the value cannot be represented by an i64, then None is returned.

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

Converts the value of self to a u64. If the value cannot be represented by a u64, then None is returned.

Provided methods

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

Converts the value of self to an isize. If the value cannot be represented by an isize, then None is returned.

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

Converts the value of self to an i8. If the value cannot be represented by an i8, then None is returned.

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

Converts the value of self to an i16. If the value cannot be represented by an i16, then None is returned.

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

Converts the value of self to an i32. If the value cannot be represented by an i32, then None is returned.

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

Converts the value of self to an i128. If the value cannot be represented by an i128 (i64 under the default implementation), then None is returned.

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. If the value cannot be represented by a usize, then None is returned.

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

Converts the value of self to a u8. If the value cannot be represented by a u8, then None is returned.

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

Converts the value of self to a u16. If the value cannot be represented by a u16, then None is returned.

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

Converts the value of self to a u32. If the value cannot be represented by a u32, then None is returned.

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

Converts the value of self to a u128. If the value cannot be represented by a u128 (u64 under the default implementation), then None is returned.

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. If the value cannot be represented by an f32, then None is returned.

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

Converts the value of self to an f64. If the value cannot be represented by an f64, then None is returned.
